Why Master Time Zone Coordination?
The rules are not intuitive
Time zones are political, not geographic. China spans five geographic zones but keeps one official time; Spain sits west of Greenwich but runs on Central European Time. You cannot infer a city's time from a map.
The rules change
Countries adopt, abolish and shift daylight saving with little notice. Turkey abandoned seasonal clock changes in 2016; Morocco shifts twice a year around Ramadan rather than for summer. Rules you memorised once go stale.
Mistakes are silent
Nothing warns you that a recurring invite drifted an hour because one side changed clocks and the other didn't. You find out when someone doesn't join the call. These guides cover how to avoid that.
Where to start
These guides are written to be read in any order, but they answer different questions and it is worth knowing which one you need.
If you keep getting meeting times wrong — start with meeting scheduler best practices. It covers the confirmation habits that remove most scheduling errors outright, including why writing "9 AM PT" in an email is not enough.
If daylight saving keeps catching you out — read the daylight saving time guide. The important part is not that clocks change, but that different regions change on different dates, creating short windows each year when the usual difference between two cities is simply wrong.
If you are setting up a distributed team — read remote work across time zones, which deals with overlap windows, rotation, and what to do when there is no shared working hour at all.
If you want the underlying mechanics — the world clock guide and time zone calculator guide explain how offsets, UTC and the IANA database actually fit together.
Guides, articles and tools
The guides on this page are reference material — they explain how something works and are meant to be returned to.
The articles are narrower and more opinionated: specific problems, worked examples, and what distributed teams actually do in practice.
The tools are for when you already know what you need and just want the answer, and the city pages carry the standing facts for a single place — its offset, whether it changes clocks, on what dates, and how its day overlaps with yours.
If you are new to the subject entirely, the basics is a shorter introduction to what time zones are and why they exist.
