What is a time zone cheat sheet?

A time zone cheat sheet is a reference table that shows the current local time in every time zone at once, so you can answer "what time is it for them?" without doing the maths yourself. This page is that sheet: it is a live world clock covering every IANA time zone, and it keeps counting so the times you read are correct right now, not cached from whenever you loaded it.

Because daylight saving shifts are handled automatically, the same table stays accurate through the March and October transitions - no need to remember which country changes its clocks and when.

How to use this world clock

• Search or filter by city, country or region to narrow the table down.
• Switch between 24-hour and 12-hour clocks, and between date formats.
• Save the zones you use most as favourites, then share that shortlist with your team.
• Use the presets to jump to a whole region at once, such as Europe or Asia.
