Dates are complex enough without times and timezones. This module may
|
||
|
|
be used to create simple date objects. It handles:
|
||
|
|
|
||
|
|
Validation:
|
||
|
|
Reject 1999-02-29 but accept 2000-02-29.
|
||
|
|
Interval arithmetic:
|
||
|
|
How many days were between two given dates? What date comes N days
|
||
|
|
after today?
|
||
|
|
Day-of-week calculation:
|
||
|
|
What day of the week is a given date?
|
||
|
|
|
||
|
|
It does NOT deal with hours, minutes, seconds, and time zones.
