Daylight saving time and the DST badge

Daylight saving time (DST) starts and ends on different dates in different countries, and some countries do not use it at all. The converter works out each city’s offset for the exact day you are looking at, so the times are right on both sides of a change.

The DST badge

When a city is about to change its clocks, its card shows a small badge with the date, for example DST Oct 25. It is a reminder that the offset between that city and the others will change on that date.

Why it matters

• Two cities can be 5 hours apart in September and 4 hours apart in November, even though neither moved.
• A weekly meeting may land an hour earlier or later for some people after one country changes its clocks and another has not yet.

Tips

• Before you schedule a recurring meeting, move the timeline to a date after the change and check the red hours again.
• On the changeover days themselves the times are still correct, because they follow the actual rules for that city.
• A shared link keeps the exact moment, so it stays right whatever the clocks do. See Share a time with your team.
