This is the template sandbox page for Template:Daylight saving active (diff). See also the companion subpage for test cases. |
This template returns either 0 or 1 to indicate if daylight saving time (DST) is active in the given time zone region:
0 | DST is not active |
1 | DST is active |
See below for the currently supported time zones. Note that if DST is only partially observed in a certain time zone, this template returns 1 if DST is active in that part (even though it is not observed/active in the other part).
During DST, the clock is set one hour ahead of standard time.
{{Daylight saving in time zone | time zone abbreviation | date/time value}}
Parameter | Description | Type | Status | |
---|---|---|---|---|
time zone abbreviation | 1 | Abbreviation of the time zone for which it is determined if DST is active. If no time zone is given or if the given time zone is not supported, then the output will default to 0.
| String | suggested |
date/time value | 2 | Date and time for which it is determined if DST would be active in the given time zone. By default, if no value is given, it is determined if DST is active at the current time.
| Date | optional |
