What is the Month?

The month is a unit of time and is a multiple of an SI base unit with the symbol mo.

There are 100s of definitions of a month that have been established, reviewed and adopted over the course of history but the most common around the world today are the months in the Julian and Gregorian calendars.

There are 12 months in the Julian and Gregorian year; averaging 30.4368 days in each. They are labelled January, February, March, April, May, June, July, August, September, October, November and December.

There is a famous rhyme to help remember how many days are in each month that goes “Thirty days has September, April, June and November – all the rest have thirty-one. Except February which has 28 or 29 in a leap year.”

Many cultures use the moon’s cycle (the lunar cycle) to define which month they are in.

What is the Sidereal Second?

The sidereal second is a unit of time used by astronomers and is derived from the SI unit system. We have used the symbol s-sr.

1 sidereal second is 1/60 of a sidereal minute. This is derived ultimately from the sidereal day which is the time taken (in solar seconds) for the Earth to complete one rotation with respect to a distant star or constellation.

Like with normal seconds, minutes, hours and days, there are still 60 x 60 x 24 seconds in a day, but the day itself is approximately 23 h 56 min and 4.1 s in (normal) seconds.
