# How many times do a clock's hands overlap in a day?

# How many times in a day are the hour hand and minute hand of a clock at right angles?

I just did some tallying in my head, with pencil and paper handy. In a 24 hour day, I count 44 times. Answer The continuous movement of the hour hand brings about something analogous to the "sidereal day" problem. Most of the time, there are 2 occurances per hour of 90 degrees between the hands. Bu…t after 2 PM, for example, there is an occurance before 2:30, and the next occurance is 3 PM. There is then one occurance after 3 PM, the next one being after 4 PM. The same thing happens again at 8 and 9. So it seems that a total of 44 is probably right. Another way to 'visualize' that 'twice per hour' can't always work is to see that occurances of 90 degrees must be farther apart than 30 minutes, because both hands are advancing, not just the minute hand. For some hours, the first occurance will be late enough in the hour that the next occurance is in the next hour. --------------------------------------------------------------------------------------- Let me show you a mathematical approach. Common sense dictates that the minute hand moves at a faster rate of 5.5 degrees a minute (because the hour hand moves 0.5 degrees a min and the minute hand moves 6 degrees a minute). We start at 12 midnight. The hands are together. For subsequent 90 degree angles to occur, the minute hand must "overtake" the hour hand by 90 degrees, then 270 degrees, then 360 + 90 degrees, then 360 + 270 degrees, then 360 + 360 +90 degrees.. and so on. This can be re-expressed as: (1)90, 3(90), 5(90), 7(90), 9(90), 11(90)... n(90). The number of minutes this takes to happen can be expressed as (1)90/5.5, 3(90)/5.5, 5(90)/5.5, 7(90)/5.5, 9(90)/5.5, 11(90)/5.5... n(90)/5.5. In one day, there are 24 hr * 60 mins = 1440mins To find the maximum value of n, n(90)/5.5 = 1440 n = 88 but as seen from above, n must be an odd number (by pattern recognition and logic) hence n must be the next smallest odd number (87) counting 1,3,5,7,9,11......87, we see that the number of terms = (87-1)/2 +1 = 44. In other words, the minute hand "overtakes" the hour hand on 44 occasions in 24 hours in order to give a 90 degree angle. Therefore the answer to your question is 44. (MORE)

# How many times do the hands of a clock overlap in a day?

A Better Approach (with reasoning) There are 2 cases depending on the working of the watch. Case 1: the movement of the second, minute and hour hands are continuous (not step-wise or click-based) Answer is: the hour and minute hands overlap every hour. .
Case 2 (very unusual): the hour hand… jumps from 1 to 2, 2 to 3, ... and so on, as soon as the minute hand crosses (or reaches 12) and the minute hand jumps from 1 to 2, 2 to 3, ... and so on, as soon as the second hand crosses (or reaches 12). Answer: every 65 minutes. Interviewers often expect this answer cos they do not think accurately. The exact times are: 0000 (12:00 AM) 0105 (01:05 AM) 0211 (02:11 AM) 0316 (03:16 AM) 0422 (04:22 AM) 0527 (05:27 AM) 0633 (06:33 AM) 0738 (07:38 AM) 0844 (08:44 AM) 0949 (09:49 AM) 1055 (10:55 AM) 1200 (12:00 PM) 1305 (01:05 PM) 1411 (02:11 PM) 1516 (03:16 PM) 1622 (04:22 PM) 1727 (05:27 PM) 1833 (06:33 PM) 1938 (07:38 PM) 2044 (08:44 PM) 2149 (09:49 PM) 2255 (10:55 PM) .
Reasoning for Case 1: ----------------------------- When do they overlap? At every (n + (n/11)) hours where n = 0, 1, 2, 3, ..., 24. How did I find this out? The following is the reasoning i used: At 0000, the hour and minute hands overlap. So number of overlaps now is 1. The minute hand races away and never again overlaps during the next one hour. Now, the minute hand moves at 360 o /hour and the hour hand moves at 30 o /hour. At 0100, the hour hand would be the 1 mark (or 30 o from the 12 mark) and the minute hand would be at the 12 mark. Starting at this position (at 0100), they would overlap when the number of degrees moved by both the minute and the hour hand are the same. Let them overlap at some time, say T, then I can write them in equation form as: 30 o + (30 o )x(T) = (360 o )x(T) How did I get to this equation? Note that, at 0100, when the minute hand starts moving from the 12 mark, the hour hand is already ahead of the minute hand by 30 o . If the minute hand moves at a speed of 360 o /hour, then in some time (T), it would cover (360 o )(T) degrees. If the hour hand hand moves at a speed of 30 o /hour, then in the same time (T), it would cover (30 o )(T) degrees. Since the hour hand is already 30 o ahead from the 12 mark, the total degrees covered by the hour hand from the 12 mark would then be (30 o + the number of degrees covered in time T) which is (30 o + (30 o )x(T)). Now the condition when the two hands will overlap is that they should have covered the same number of degrees at a moment (or) No. of degrees covered by minute hand = No. of degrees covered by hour hand (or) .
30 o + (30 o )x(T) = (360 o )x(T) .
If you solve this equation to find the value of T, you would get 30 o = (360 o )x(T) - (30 o )x(T) 30 o = (360 o - 30 o ) x T 30 o = 330 o x T (or) T = 30 o /330 o T = 1/11 At 0200, the hour hand would be the 2 mark (or 60 o from the 12 mark) and the minute hand would be at the 12 mark. Starting at this position (at 0200), they would overlap when the number of degrees moved by both the minute and the hour hand are the same. Let them overlap at some time, say T, then I can write them in equation form as: 60 o + (30 o )x(T) = (360 o )x(T) Solving this equation, you will the value of T = 2/11 At 0300, using the same reasoning (the hour hand at 90 o past the 12 mark) and modifying the equation accordingly (90 o + (30 o )x(T) = (360 o )x(T)), you would get the answer for T = 3/11. In general, the value for T for every hour is T = n/11 where n = 0, 1, 2, 3, ..., 24. So the exact time when the two hands overlap can be written as: the hour (n) + the time taken during that hour (T) .
(or) n + n/11 where n = 0, 1, 2, 3, ..., 24. .

In a day, the hands would only overlap 22 times, as illustrated in the table above. I would propose that the hands always overlap, as they're both attached at the center of the dial. If you didn't want to be facetious (or, at least, less facetious), you would still have to ask how many hands were on the clock. It may have a second hand, for example, or be digital (no hands at all). (MORE)

# Can a VCR clock's time change by itself if it does not have a automated system that might change it on its own?

It can if the power goes out while you're not home. If the power goes out some VCR's will go to all 8's and some will go to 12:00 and start telling time. If that happens it will look like it changed the time by itself.

# How many time hour hand and minutes hand cross each other in 1 day or 24 hours?

23 times..
The time interval between each 'meeting' of the minute and hour hands is 65minutes and 27.272727(recurring) seconds.
There are number of ways of working this out. But my method allows you to calculate this mentally..
it takes 60 minutes for a minutes hand to complete 360 degrees. ie 36…0/60 = 6 degrees per minute..
and 12 * 60 minutes (12 hours) for a hours hand to complete 360 degrees. ie 360 / (60*12) = 0.5 degrees per minute.
so the relative speed of minutes hand with respect to hours hand is 6-0.5 = 5.5 degrees per minute..
Now time taken to complete 360 degress gives you the time interval between each meeting of both the hands and that is.
360/5.5 = 65.45 minutes . TADA !! (MORE)

# Imagine an analog clock set to 12 o'clock Note that the hour and minute hands overlap. How many times each day do both the hour and minute hands overlap How would you determine the exact times?

The hands do not overlap between 11 to 12, so only 22 overlaps per day. ---------------------------------.

(as Digbybare said, and not 24 as i was said at first) Exact times = Hour : ( Hour * 65 / 12 ) that is, when it is "1:05", the hour hand has moved from '1' to '2' (that total distance is 5 minutes) as the minute hand has moved from '12' to '1' (that is exactly 5 minutes, or Hour * 5); so the Hour hand must has moved "Hour / 12" of the 5 minutes: = Hour : [ (Hour * 5) + (Hour / 12) * 5 ] = Hour : [ (Hour * 5) + (Hour * 5) / 12 ] => we take out the common (Hour * 5) = Hour : [ (Hour * 5) * (1 + 1/12) ] = Hour : [ (Hour * 5) * 13/12 ] = Hour : (Hour * 65/12). ------------------------- So the Successive exact time should be 1 : ~5.4 2 : ~10.8 3 : 16.25 4 : ~21.67 5 : ~27.08 6 : 32.5 ......,and so on.

# How many times a day does a clock's hands overlap?

Answer is: the hour and minute hands overlap every 65 minutes. Interviewers often expect this answer because they do not think accurately. The exact times are: 0000 (12:00 AM) 0105 (01:05 AM) 0211 (02:11 AM) 0316 (03:16 AM) 0422 (04:22 AM) 0527 (05:27 AM) 0633 (06:33 AM) 0738 (07:3…8 AM) 0844 (08:44 AM) 0949 (09:49 AM) 1055 (10:55 AM) 1200 (12:00 PM) 1305 (01:05 PM) 1411 (02:11 PM) 1516 (03:16 PM) 1622 (04:22 PM) 1727 (05:27 PM) 1833 (06:33 PM) 1938 (07:38 PM) 2044 (08:44 PM) 2149 (09:49 PM) 2255 (10:55 PM) .
Case 1: the movement of the second, minute and hour hands are continuous (not step-wise or click-based) .
Case 2 (very unusual): the hour hand jumps from 1 to 2, 2 to 3, ... and so on, as soon as the minute hand crosses (or reaches 12) and the minute hand jumps from 1 to 2, 2 to 3, ... and so on, as soon as the second hand crosses (or reaches 12). Reasoning for Case 1: ----------------------------- When do they overlap? At every (n + (n/11)) hours where n = 0, 1, 2, 3, ..., 24. How did I find this out? The following is the reasoning i used: At 0000, the hour and minute hands overlap. So number of overlaps now is 1. The minute hand races away and never again overlaps during the next one hour. Now, the minute hand moves at 360 o /hour and the hour hand moves at 30 o /hour. At 0100, the hour hand would be the 1 mark (or 30 o from the 12 mark) and the minute hand would be at the 12 mark. Starting at this position (at 0100), they would overlap when the number of degrees moved by both the minute and the hour hand are the same. Let them overlap at some time, say T, then I can write them in equation form as: 30 o + (30 o )x(T) = (360 o )x(T) How did I get to this equation? Note that, at 0100, when the minute hand starts moving from the 12 mark, the hour hand is already ahead of the minute hand by 30 o . If the minute hand moves at a speed of 360 o /hour, then in some time (T), it would cover (360 o )(T) degrees. If the hour hand hand moves at a speed of 30 o /hour, then in the same time (T), it would cover (30 o )(T) degrees. Since the hour hand is already 30 o ahead from the 12 mark, the total degrees covered by the hour hand from the 12 mark would then be (30 o + the number of degrees covered in time T) which is (30 o + (30 o )x(T)). Now the condition when the two hands will overlap is that they should have covered the same number of degrees at a moment (or) No. of degrees covered by minute hand = No. of degrees covered by hour hand (or) .
30 o + (30 o )x(T) = (360 o )x(T) If you solve this equation to find the value of T, you would get 30 o = (360 o )x(T) - (30 o )x(T) 30 o = (360 o - 30 o ) x T 30 o = 330 o x T (or) T = 30 o /330 o T = 1/11 At 0200, the hour hand would be the 2 mark (or 60 o from the 12 mark) and the minute hand would be at the 12 mark. Starting at this position (at 0200), they would overlap when the number of degrees moved by both the minute and the hour hand are the same. Let them overlap at some time, say T, then I can write them in equation form as: 60 o + (30 o )x(T) = (360 o )x(T) Solving this equation, you will the value of T = 2/11 At 0300, using the same reasoning (the hour hand at 90 o past the 12 mark) and modifying the equation accordingly (90 o + (30 o )x(T) = (360 o )x(T)), you would get the answer for T = 3/11. In general, the value for T for every hour is T = n/11 where n = 0, 1, 2, 3, ..., 24. So the exact time when the two hands overlap can be written as: the hour (n) + the time taken during that hour (T) .
(or) n + n/11 where n = 0, 1, 2, 3, ..., 24. .

It may have a second hand, for example, or be digital (no hands at all). 22 times a day if you only count the minute and hour hands overlapping. The approximate times are listed below. (For the precise times, see the related question.) 2 times a day if you only count when all three hands overlap. This occurs at midnight and noon. am 12:00 1:05 2:11 3:16 4:22 5:27 6:33 7:38 8:44 9:49 10:55 pm 12:00 1:05 2:11 3:16 4:22 5:27 6:33 7:38 8:44 9:49 10:55 A really simple way to see this is to imagine that the two hands are racing each other around a track. Every time the minute hand 'laps' the hour hand, we have the overlaps we want. So, we can say that the number of laps completed by the minute hand every T hours, Lm = T laps. Since there are 12hours in a full rotation of the hour hand, that hand only rotates Lh = T/12 laps. In order for the first 'lapping' to occur, the minute hand must do one more lap than the hour hand: Lm = Lh +1, so we get T = T/12 + 1 and that tells us that the first overlap happens after T = (12/11) hours. Similarly, the 2nd lapping will occur when Lm = Lh + 2. In general, the 'Nth' lapping will occur when Lm = Lh +N, which means every N*(12/11) hours (for N = 0,1,2,3...). In other words, it will happen approximately every 1hr5mins27secs, starting at 00:00. In 24hours, this occurs a total of 24/(12/11) = 22 times. ====== The same thing is explained below in a slightly less intuitive manner, using angular frequency: ====== So we are looking at two rotating hands. Ultimately, its just the angles we care about. Let Î¸H represent the angle of the hours hand and Î¸M represent the angle of the minutes hand. You could also introduce the seconds hand but that makes the problem more complicated. For now, lets assume the question only cares about the minute and hour hands. Initially we might think we are looking for: Î¸H=Î¸M But this doesn't take into account that if one hand has "gone around" a few times, its angle will be different from a hand in the same position that hasn't "gone around" the same number of times. So we have to modify our goal. Instead we let the angles differ by an integer multiple of 2Ï (360Â°). Let us call this arbitrary integer z. Now our condition is: Î¸M-Î¸H=2Ïz You could subtract the two angles in either order but the reason I chose to subtract hours from minutes is because it will result in positive integers which is just simpler. The minute hand goes around more times, thus its angle is bigger, thus this order of subtraction is positive. Now we have to find out how these angles depend upon the time. Let us call our time t and measure it in hours. I omit units for simplicity. The hour hand goes around a full rotation (2Ï) once every 12 hours. So: Î¸H=(2Ï/12) t For those more versed in mathematics, 2Ï/12 is the "angular frequency" for the hour hand (usually denoted by Ï). Similarly the minute hand goes around a full rotation (2Ï) once every hour. So: Î¸M=2Ï t Plugging back in: Î¸M-Î¸H=2Ïz 2Ï t - (2Ï/12) t = 2Ïz t - t/12 = z (11/12) t = z Now we are ready to solve. The two hands overlap at every solution of this equation, so we want to know the number of solutions of this equation. But remember, we want to know how many times this happens in a single day, so t cant be bigger than 24 (remember we are measuring t in hours), and technically no smaller than 0 (assuming we start our clock at 0 hours). Since t and z are proportional, each solution for z corresponds to exactly one solution for t, and accordingly exactly one solution of the equation. Also, remember than z must be an integer. So if we wanted all the times we would just let z go from 0 (when t=0) up and solve for t and stop as soon as we passed t=24. Then of course we'd have to convert that into hour and minute format. However, we only care about the number of times this happens. So we can notice that as t increases, z is just keeping track of how many times the two hands have overlapped. When z=0 we get the first time, when z=1 we get the second time, and so on. Since t and z are directly proportional, t increases with z, thus z represents the number of times the hands have overlapped up until time t minus 1 (and starting from t=0). Since we don't want t to go past 24, we plug in 24 and solve for z which will tell us how many times this event has occurred from t=0 to t=24 (one day). (11/12)*24 = z 22 = z So this happens 22 times in a day. Technically this has 23 solutions (0 through 22) but the last one is for t=24 which has begun the next day. If we don't count that solution we are left with 22.â If we want the second hand to overlap as well, we have to go a bit further. First we note that the second hand makes a full rotation once every minute, thus 60 times an hour. From this we have: Î¸S=(2Ï*60) t We want the second and hour hands to overlap AND the minute and second hands to overlap. Those conditions can be summarized as follows, where x and y are positive integers: Î¸S-Î¸M=2Ïx Î¸S-Î¸H=2Ïy Plugging in our functions of t for the Î¸'s and solving for t we are left with: t=x/59 t=12y/719 We want our integers x and y to produce the same time (making all hands overlap at that time). So we want to set the two equations equal. Simplifying, we get; x=708y/719 708 and 719 are coprime (719 is prime and 708 is decomposed into 2^2*3*59). In fact 708y and 719 are coprime except for when y is an integer multiple of 719. Thus 708y/719 can only be reduced when y=719k for some integer k. In this case we have: x=708k The first solution is when k=0. Then x=0 and t=0 corresponding to midnight. The next solution is k=1. Then x=708 and t=12 corresponding to noon. The next solution is k=2 but this corresponds to t=24 which is (midnight for) the next day and due to the direct proportionality of t and k, every k from here on up will produce t's higher than 24. In summary, all three hands only overlap twice a day: at noon and midnight. â All of this assumes that the hands sweep continuously. So the math is more(?) complicated for those with fake Rolex's (or any ticking handed clocks). Starting at 00:00 (midnight) with overlapping hands. At noon the hands have overlapped an additional 12 times and at midnight another additional 12 so including the starting and finishing midnight overlaps, 25 times . . (MORE)

# How many time hour hand and minutes hand cross?

22 times. hour hand meets minute hand each hour. Example : they meet at about 1h6, 2h17,... ( it's not exactly). But the 11th hour, they don't meet any times. So in a round of hour hand, it meets minute hand only 11 times and 22 times in a day

# How can the days overlap in the new zodiac signs?

So many people are wondering! First, I'd like to say that if you are reading your horoscope, you will still read your original sign. If you were born a Pisces, you are still a Pisces; your sign is determined by the position of the sun the moment you were born. Since you can't change the sky or y…our birthday, you're still a Pisces. As far as the dates overlapping, well, because the signs don't change at exactly midnight at the end of the period, and because people born on the edge of the sign, or cusp, often show traits from both signs, so I figure that its more efficient and logical that the days should just overlap. I say this because say you are born on March 11 at 1am, and the sign doesn't switch to Pisces until 3am, you're technically still an Aquarius, though you will most likely have strong Pisces tendencies! The dates overlap because of an error by the astronomer who proposed the new system. Whether this is a joke he is playing on astrology buffs remains to be seen. The new dates have been widely reported and there seems to be little if any recognition of the error. The lack of critical reading by both the public and the reporters is truly amazing. (MORE)
