Timezone names are specified by IANA, please see for more information and communication channels.

IANA is lagging behind, and we'll take care of them as well. The official name is Kyiv, and every authority is liable to adhere to that guidance. Two years have passed since its adoption - a time more than well sufficient to comply.
Meanwhile, other sources have already complied (e.g., in Microsoft Windows, as of the version 10, if you look into the Date & time settings => Time zone dropdown contains the following entry:
 '(UTC+02:00) Helsinki, Kyiv, Irga, Sofia, Tallinn, Vilnius'

Also, I've submitted a patch, so, hope, this change will be applied into one of the nearest releases.

Thanks a lot in advance and have a nice week!

Windows does not use IANA identifiers for their timezones.

This will only change in PHP if IANA changes it, and then automatically. If IANA doesn't change it, PHP won't either.

The Ukrainian cities listed in the timezones are using Russian spelling,
not Ukrainian spelling.

Kiev -> Kyiv
Uzhgorod -> Uzhhorod
Zaporozhye -> Zaporizhzhia

IANA and ICANN have been contacted. It would be helpful for PHP to reach out as developers as well. It is a problem because the spelling is a political statement for a lot of people/businesses. There is a war between Russian and Ukraine. By having these spellings listed through, your company is also taking a political position.

In the IANA database (TZDB) time zones starting from version 2022b, the Zone ID was changed to "Europe/Kyiv". "Europe/Kiev" is currently only listed as an alias.
