Release notes

Sourced from tzdata's releases.

2023.3: Release of upstream tzdata 2023c

Version 2023.3

Upstream version 2023c released 2023-03-28T19:42:14+00:00

Changes to past and future timestamps

Model Lebanon's DST chaos by reverting data to tzdb 2023a. (Thanks to Rany Hany for the heads-up.)

2023.2: Release of upstream tzdata 2023b

Version 2023.2

Upstream version 2023b released 2023-03-24T02:50:38+00:00

Briefly:

Lebanon delays the start of DST this year.

Changes to future timestamps

This year Lebanon springs forward April 20/21 not March 25/26. (Thanks to Saadallah Itani.)

2023.1: Release of upstream tzdata 2023a

Version 2023.1

Upstream version 2023a released 2023-03-22T19:39:33+00:00

Briefly:

Egypt now uses DST again, from April through October. This year Morocco springs forward April 23, not April 30. Palestine delays the start of DST this year. Much of Greenland still uses DST from 2024 on. America/Yellowknife now links to America/Edmonton. tzselect can now use current time to help infer timezone. The code now defaults to C99 or later. Fix use of C23 attributes.

Changes to future timestamps

Starting in 2023, Egypt will observe DST from April's last Friday through October's last Thursday. (Thanks to Ahmad ElDardiry.) Assume the transition times are 00:00 and 24:00, respectively.

In 2023 Morocco's spring-forward transition after Ramadan will occur April 23, not April 30. (Thanks to Milamber.) Adjust predictions for future years accordingly. This affects predictions for 2023, 2031, 2038, and later years.

This year Palestine will delay its spring forward from March 25 to April 29 due to Ramadan. (Thanks to Heba Hamad.) Make guesses for future Ramadans too.

Much of Greenland, represented by America/Nuuk, will continue to observe DST using European Union rules. When combined with Greenland's decision not to change the clocks in fall 2023, America/Nuuk therefore changes from -03/-02 to
