Make use of the different systems by combining a reference system type flag with an appropriate ID. Read about the syntax to get the details.
At this point we provide only a entirely superficial description of PostTIME's calendar systems. Please look up the details some where else.

---|---|---|
1 | Gregorian calendar | This system is the standard calendar in many countries as well as on the international level. |
2 | Julian calendar | In the most European countries this calendar was in use before the Gregorian calendar was introduced. In some domains it is still in use. |
ID | Name | Origin | Unit |
---|---|---|---|
1 | Julian Day | -4713-01-01 in the Julian calendar | Day |
