what's a relationship between days,hours and seconds?

I was going to write this all out to explain it to you, but this website said exactly what I was going to say, but better and with more detail...\n\n"Base 60 (Sexagesimal) Numbering system\n\nThe Sumerian culture developed the Sexagesimal Numbering system some 4000 to 6000 years ago. This system was developed into a rigorous numbering system. The digits used were symbols which represented syllables instead of letters that were pressed into clay tablets. There were symbols representing ones and tens and were combined to represent the number of each place value.  See the following site for more information about the Sumerian numbering system. http://it.stlawu.edu/~dmelvill/mesomath/index.html\n\nEach place value to the left is equal to 60 times the place value to the right which implies that each place value to the right is equal to the place value to the left divided by 60. It was up to the context of the number to determine where the place values began. Also, the place values may be fractions of base 60 numbers, ie. 1/60, 1/3600, etc.\n\n3600, 60, 1, 1/60, 1/3600 \n\nThe use of 60 as a grouping number was used by many cultures throughout our earth's history. This may be because 60 has many factors, including 12 (which also has many factors) and was convenient to use for trading, counting, etc. because of its divisibility. Our notations of time into 60 seconds and 60 minutes uses a from of this numbering system, but is not as rigorous because of the 24 for hours and the subdivisions of seconds into milliseconds, etc."

Time is the number of occurence of one event  relative to another event such as the number of earth revolutions around the sun relative to the number of revolutions of another planet, say Pluto, around the sun.

In the northern Hemisphere the days are longer during the summer months and shorter in the winter months.  The opposite is true in the Southern Hemisphere.  To get exactly length of the day I think you would need a computer program.  The calculation seems a bit complicated.

First of all, lets just look at 12 hrs, as it will be the same for the next twelve:\n\nThe minute hand revolves around the clock at 1 rev per 60 minutes, the hour hand revolves around at 1 rev per 60•12 minutes.  Knowing that after 60 minutes the minute hand is back to where it started we can say that 2π≡0.  We want to rewrite the above relations to give us the positions as a value of time.  This can be done by assuming that t is time (in minutes) and using m=2π/60t (minute hand) and h=2π/(12•60)t (hour hand).  \nTherefore we want to solve m=h+2πk for some integer 0≤k≤10.  The reason that we don't have k go to 11 is because if you think about it, the hour and minute hand never cross during the 11th hour, they keep getting closer, but then at 12:00 (during the 12th hour) they meet.\n\nThus 2π/60t=2π/(12•60)t+2πk ==>> 12t=t+720k ==>>11t=720k ==>> t=720/11k.\n\nNow, this is the time after 12:00 (midnight or noon, I don't care they; are the same). \nThese times are:\n\n12:00 (k=0)\n1:60/11=1:05:300/11≈1:05:27.27 (k=1)\n2:10:600/11≈2:10:54.55\n3:16:240/11≈3:16:21.81\n4:21:540/11≈4:21:49.09\n5:27:180/11≈5:27:16.36\n6:32:480/11≈6:32:43.64\n7:38:120/11≈7:38:10.91\n8:43:420/11≈8:43:38.18\n9:49:60/11≈9:49:05.45\n10:54:360/11≈10:54:32.73\n\nI decided to give you the second values as fractions also, since they can't be given accurately by a terminating decimal.

The english came up with the seconds and minutes thing.\n\nA "minute" is a "minute fraction" (1/60) of an hour. 60 was chosen for being easily divisible into two, three, four, five, and six parts. A "second" is a "second minute fraction" of an hour (1/60*1/60 = 1/3600).\n\nI believe that the romans were the first to use a system of 24 hours. 24 was selected, again, for being easily divisible into two, three, four, and six parts.

For some uses of the word "day" there are no synonym.  For others:\nperiod\ninterval\ntime\n24-hour

I'll take a simpler interpretation of the question and say one second is "calculated" to be 1/86400th of a day, where 86400 is the product of 24 hours times 60 minutes/hour times 60 seconds/minute. Problem is that the day (say from local noon to local noon by measuring the sun's highest point in the sky) is not constant throughout the year, so it was decided to use the average day looking over the whole year. \nFor very precise timings of experiments in the laboratory, one needs a very good pendulum or something else that oscillates or vibrates at a very constant frequency; then you can work back to what fraction of a day or how many seconds something takes. \nIn modern times cesium atoms provided the constant well defined measurable frequency, and scientists agreed to "define" one second as some number of these oscillations (9,192,631,770). Now when the earth decides to rotate at a different rate, scientists add leap seconds instead of redefining the second every year. \nLately the reliability of the cesium atom has been questioned, and since the speed of light (in vacuum) is defined as a fundamental "constant", the second can indeed be defined as how long it takes light to go some distance (299,792,458 meters), but that seems circular to me because I see a meter defined as how far light goes in 1/299,792,458 of a second.

So simple.... The letter "E" ...\n\nThe day means...sunday monday, tuesday, wednesday, thursday, and so on....\n\nTuesday have one "E" and Wednesday have two "E" so there are 3 "E" in day... \n\nAnother way to justify this is by listing morning, afternoon, evening and night. if you count the "E" there are 3 "E".\nSo that explains it...Am i right guys?...

Are those times?  As in, one hour, 24 minutes, and 43 seconds?  In that case, I would say that 1:24:43 minus 1:22:05 is 0:02:38.  You come up with this answer by subtracting the first numbers (1-1), then the second numbers (24-22), and then the third numbers (43-05).  This way, you're subtracting hours from hours, minutes from minutes, and seconds from seconds - they have to match up.

It is called the equation of time. It isn't really statistics though.

I think he meant to ask why a day is divided into 24 and not 36 or 48. The actual time would be the same but there would be short intervals. A half hour would end up being an hour. Why divide a circle into 360 or an hour into 60. \n\nHour :- "a traditional unit of time, equal to 60 minutes, or 3600 seconds, or 1/24 day. The custom of dividing the daylight into 12 hours goes back at least as far as the Babylonians, who liked to divide units by 12 because groups of 12 are easily divided into halves, thirds, or fourths. Originally an hour was 1/12 of the time between sunrise and sunset, so summer hours were longer than winter hours. Later, when people wanted to express times at night, it was natural to divide the night into 12 hours as well, making 24 hours in the day. Only after the invention of mechanical clocks, around 1300, did hours became equal intervals marked by clocks. The word comes from an ancient Greek word hora which originally meant a season, especially a religious season, and hence a "defined" period of time. In the Christian church hora came to mean one of the services held at seven specific times during the day, thus establishing the word as marking subdivisions of the day."
