A Date field may contain any date of the Gregorian calendar.

When a Date field's value is used in a Calculation field, the value used is that used by Unix and Linux systems to represent dates. which is the number of seconds before or since January 1, 1970. When a Date field's value is used in a JavaScript field or in Memento scripts, the value used is based on that used by Unix and Linux systems to represent dates, but is in milliseconds (instead of seconds) before or since January 1, 1970.

This value allows date arithmetic to work readily, by merely doing integer arithmetic with the value.

When a date value is interpreted for import, export, or display in years, months, and days, the current locale is used. The format for import and export can be specified in program settings.
