Worldwide Daylight Saving Abolition Trends
EU, US, Turkey, Russia, Mexico — who dropped DST and what it means for scheduling.
Daylight saving is not permanent. Russia fixed offsets since 2014; Turkey has changed policy repeatedly; most of Mexico stopped switching after 2022; the EU debated abolition without full adoption. US states discuss permanent standard time. For users, **outdated blog posts beat wrong math** — trust IANA, not memory.

What you should do
- Schedule from current IANA rules, not "how it was last year"
- Contracts: IANA or UTC, not aging abbreviations
- Headlines "country drops DST" — confirm effective date and scope
- Use Convert with **future dates** for long projects
