How long is a lunar day?
81485
If you are asking "How long is one day on the moon?", i.e. how long does it take the moon to rotate on its axis, the answer 29 days, 12 hours, 44 minutes and 3 seconds long, the same as the period from full moon to full moon.

the lunar cycle is just about 28 days, not exactly though. Allowing for it to be 28. divide 365 by 28 and you have 13.  So depending on what phase of the moon you have at the start of the year, you will have 13 of them that year. Consequently each year will start with a different phase so you will have 13 different ones each year. Allow for the fact that the lunar month is not exactly 28 days even adds to the situation. On occasion you will have two full moons in one calender month, a "Blue Moon".  Each full moon has a name for it based on folk lore and legends. Harvest moon, the full moon closest to autumn to allow light for harvesting later....etc. A tidbit of info....the moveable holiday of Easter can always be determined as the first Sunday, after the first Full Moon after the beginning of Spring.

There is no day of the year that has EXACTLY 12 hours of daylight and 12 hours of dark because no day is EXACTLY 24 hours long. A sidereal day is 23 hours, 56 minutes, 4.091 seconds long. On the equinoxes, we have approximately equal amounts of light and dark.

No, there is  24 hours over the period of 4 years which we dont account for on a daily basis but it gets added to our calender every 4 years & that year would be called a leap year. The day it falls on would be 29th February which will not be present for the other 3 years.

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.

it is actuall slightly less that 24 hours, it is exactly\n\n23 hours, 56 minutes and 4.09 seconds\n\nthat is why we have a leap year built into our calender, to offset the difference between the 24 hour clock and the actual rotational period of the earth

You want exactly 8:23 but didn't say what time zone. At 8:23 am UT, which is the same as Greenwich Mean Time, the Moon was 62.3 Earth radii away. The mean diameter of the Earth is 12,742 km which gives a radius of 6,371 km so the distance to the Moon is 62.3 * 6,371 = 396,913 km or 246,755 miles. You can use the source to get the distance for some other time. After entering the date and time (UT is GMT which is the time in London, England), see the table at the bottom for the distance.

The moon's distance from earth is about 240,000 miles.  The orbit is roughly circular (only 5% eccentricity), so 2π*240,000 = 1.5 million miles is the circumference.  The moon travels this distance in 29.5 days, so its speed is about 51,000 miles per day or about 2100 miles per hour.

depending on the day of the week anywhere from 1 to 4 hours.

To understand how the moon rises and sets you need to be aware that the moon rotates around the earth and that the moon and the earth, together with all the other planets, rotate around the sun.\n\nIt takes 24 hours for the earth (complete with the moon) to rotate around the sun.  The actual time is closer to 24 hours and 57 seconds but that's by the by.\n\nObviously each morning the sun rises and each evening it sets again - it's very much the same with the moon only the moon doesn't work on a 24 hour cycle.\n\nThe time it takes the moon to make a complete orbit around the earth varies depending on the time of year but it averages 24 hours and 50 minutes.  If the moon were to set today at 1.00pm then it would set tomorrow at 1.50pm, 2.40pm the next day and so on.\n\nDepending where you are on the planet the moon will rise and set at differnt times.  The moon rise times for the next few days in New York and LA are...\n\nMonday  11.39 in NY,  09:07 in LA\nTuesday  12:33 in NY,  10:03 in LA\nWednesday  13:33 in NY,  11:02 in LA\nThursday  14:37 in NY,  12:02 in LA\nFriday  15:41 in NY,  13:02 in LA\n\nAll times are PST\n\nSo in some ways the moon is similar to the sun in that it's always there but it's not always visible because it's around the other side of the earth.\n\nOften the moon is in the sky during the daytime (as it will be for the next few days) but it's not clearly visible as it's so dim in comparison to the sky.

A day is 24 hours long. However, the amount of daylight varies tremendously. In summer, there is 24 hours of daylight in the Midnight Sun period. In midwinter, there is polar night where the sun never goes over the horizon.

It takes the Moon 27.322 days to go around the Earth once. Because of this motion, the Moon appears to move about 13° against the stars each day, or about one-half degree per hour. If you watch the Moon over the course of several hours one night, you will notice that its position among the stars will change by a few degrees.

The Seven-Day Week\n\nThe Babylonians marked time with lunar months. They proscribed some activities during several days of the month, particularly the \nfirst -- the first visible crecent,\nseventh -- the waxing half moon,\nfourteenth -- the full moon,\nnineteenth -- dedicated to an offended goddess,\ntwenty-first -- the waning half moon,\ntwenty-eigth -- the last visible crecent,\ntwenty-nineth -- the invisible moon, and\nthirtieth (possibly) -- the invisible moon. \n\nThe major periods are seven days, 1/4 month, long. This seven-day period was later regularized and disassociated from the lunar month to become our seven-day week. \n\nThe Naming of the Days\n\nThe Greeks named the days week after the sun, the moon and the five known planets, which were in turn named after the gods Ares, Hermes, Zeus, Aphrodite, and Cronus. The Greeks called the days of the week the Theon hemerai "days of the Gods". The Romans substituted their equivalent gods for the Greek gods, Mars, Mercury, Jove (Jupiter), Venus, and Saturn. (The two pantheons are very similar.) The Germanic peoples generally substituted roughly similar gods for the Roman gods, Tiu (Twia), Woden, Thor, Freya (Fria), but did not substitute Saturn. \n\nSunday -- Sun's day\nMiddle English sone(n)day or sun(nen)day\nOld English sunnandæg "day of the sun"\nGermanic sunnon-dagaz "day of the sun"\nLatin dies solis "day of the sun"\nAncient Greek hemera heli(o)u, "day of the sun"\n\nMonday -- Moon's day\nMiddle English monday or mone(n)day\nOld English mon(an)dæg "day of the moon"\nLatin dies lunae "day of the moon"\nAncient Greek hemera selenes "day of the moon"\n\nTuesday -- Tiu's day\nMiddle English tiwesday or tewesday\nOld English tiwesdæg "Tiw's (Tiu's) day"\nLatin dies Martis "day of Mars"\nAncient Greek hemera Areos "day of Ares"\n\nTiu (Twia) is the English/Germanic god of war and the sky.
