python/tzdata (tzdata)
v2026.3: : Release of upstream tzdata 2026cCompare Source
Version 2026.3
Upstream version 2026c released 2026-07-08T17:23:58+00:00
Briefly:
Alberta moved to permanent -06 on 2026-06-18. Morocco moves to permanent +00 on
2026-09-20. More integer overflow bugs have been fixed in zic.
Changes to future timestamps
Alberta’s 2026-03-08 spring forward was its last foreseeable clock change, as it
moved to permanent -06 thereafter. (Thanks to Roozbeh Pournader and others.)
Model this with its traditional abbreviation CST. Although the change to
permanent -06 legally took place on 2026-06-18, temporarily model the change to
occur on 2026-11-01 at 02:00 instead, for the same reason we introduced a
similarly temporary hack for British Columbia in 2026b.
Although another TZDB release will likely be needed soon because Northwest
Territories will likely follow Alberta, the legal formalities have not yet taken
place.
Morocco plans to move back to permanent UTC, without daylight saving time
transitions, on 2026-09-20 at 02:00. This also affects Western Sahara.
Changes to commentary
Northwest Territories is expected to move to permanent -06 prior to 2026-11-01
02:00, when clocks would otherwise fall back. (Thanks to Tim Parenti and James
Bellaire.) Model this with its traditional abbreviation CST. Unfortunately the
change is not yet official, so it is currently present only as comments that can
be uncommented as needed.
v2026.2: : Release of upstream tzdata 2026bCompare Source
Version 2026.2
Upstream version 2026b released 2026-04-23T06:06:43+00:00
Briefly:
British Columbia moved to permanent -07 on 2026-03-09. Some more overflow bugs
have been fixed in zic.
Changes to future timestamps
British Columbia’s 2026-03-08 spring forward was its last foreseeable clock
change, as it moved to permanent -07 thereafter. (Thanks to Arthur David Olson.)
Although the change to permanent -07 legally took place on 2026-03-09,
temporarily model the change to occur on 2026-11-01 at 02:00 instead. This
works around a limitation in CLDR v48.2 (2026-03-17). This temporary hack is
planned to be removed after CLDR is fixed.
v2026.1: : Release of upstream tzdata 2026aCompare Source
Version 2026.1
Upstream version 2026a released 2026-03-02T06:59:49+00:00
Briefly:
Moldova has used EU transition times since 2022. The "right" TZif files are no
longer installed by default. -DTZ_RUNTIME_LEAPS=0 disables runtime support for
leap seconds. TZif files are no longer limited to 50 bytes of abbreviations. zic
is no longer limited to 50 leap seconds. Several integer overflow bugs have been
fixed.
Changes to past and future timestamps
Since 2022 Moldova has observed EU transition times, that is, it has sprung
forward at 03:00, not 02:00, and has fallen back at 04:00, not 03:00. (Thanks
to Heitor David Pinto.)
Changes to data
Remove Europe/Chisinau from zonenow.tab, as it now agrees with Europe/Athens for
future timestamps.
v2025.3: : Release of upstream tzdata 2025cCompare Source
Version 2025.3
Upstream version 2025c released 2025-12-10T22:42:37+00:00
Briefly:
Several code changes for compatibility with FreeBSD.
Changes to past timestamps
Baja California agreed with California’s DST rules in 1953 and in 1961 through
1975, instead of observing standard time all year. (Thanks to Alois Treindl.)
Changes to commentary
The leapseconds file contains commentary about the IERS and NIST last-modified
and expiration timestamps for leap second data. (Thanks to Judah Levine.)
Commentary now also uses characters from the set –‘’“”•≤ as this can be useful
and should work with current applications. This also affects data in
iso3166.tab and zone1970.tab, which now contain strings like “Côte d’Ivoire”
instead of “Côte d'Ivoire”.
