Yes, a full day is equivalent to 24 hours.

No.

6 minutes * 60 seconds/minute = 360 seconds

3155760000000 milliseconds.

80 Hours or 3 and a third days.

One day is equal to 60 x 60 x 24 = 86400 seconds. Therefore, 36000 seconds is equal to 36000/86400 = 5/12 of a day, or 0.416 recurring (that is, 0.416666..) days.

16,666,666.6667 minutes.

There are 1 hour and 40 minutes in 100 minutes. Meaning 100 minutes = 1 hour and 40 minutes.

48

There are 24 hours in a day
2 days = 24 x 2, which equals 48.

20,000 hours is just over 833 days (833.333333333 days)

4 minutes.

So there are 12 months in a year. There is on average 365.25 days in a year. Therefore 365.25 / 12 is 30.4375 days per month avr. This *24*60*60 is 2,629,800 seconds in a month.

30 days = 43,200 minutes

Not sure about a melenium - whatever that is, but there are approx 31557600000000 milliseconds in a millennium. The exact number depends on how many leap years there were in the interval and on whether or not there were any leap seconds.

Disregarding the second hand (for a few seconds), the hour and minute hands overlap (point in the same direction) 22 times in a 24 hour period. It happens once after every hour except the 12 o'clock hour. After 12 o'clock, the next occurance is after 1 o'clock. The fractions of a minute required for these overlaps do not always coincide with the number of seconds that the second hand would have to register in order for the second hand to 'join' the hour and minute hands. The only times that all three hands are perfectly overlapping (pointing in the same direction) is at 12 midnight and 12 noon. So the second minute and hour hands are in the exact same place only twice during every 24 hour period. The hour and minute hands join each other every 65.454545 minutes, or 32.727272 degrees. The minute hand advances 163.636363 degrees each time the hour and minute hands overlap.

There are 720 hours in the month of April.

The week starts on a Sunday on most North American calendars, since the norm is to begin with the Christian sabbath. (But if you are Jewish, the new week starts on a Saturday, since that is their Sabbath, while for Muslims, it's a Friday.) However, it should be noted that some people regard the start of the week as Monday, the day when most people go to work: in western cultures, the Monday-through-Friday schedule is widely observed in businesses and schools.
