The Julian date calendar calculates the number of days and fractions of days elapsed since Greenwich noon of January 1, 4713 BC. This is probably the simplest calendar possible. The exact date can be a single integer, while date and time in the Julian day calendar are represented by just one number. With this calendar, it is easy to determine day of week by performing a simple mathematical calculation. The remainder upon division by 7 would represent the day of the week, with 0 being Monday and 6 being Sunday.

The JD calendar makes it very easy to calculate the difference between any two dates. Simply subtracting one date from another gives the number of days and fractions of a day passed between the two dates. JD calendar is easy to be converted into any other calendar due to its simplicity. The Julian day system is widely used by astronomers and the military to provide a mathematically straightforward system of dates. It is also employed by historians to work with the many different calendars invented throughout human history. Julian day and Julian date have no relation to the Julian calendar apart from the name and the zero day.
