Does this converter account for daylight saving time?

Yes, the conversion reflects whether daylight saving time is active in each location for the date being converted, since fixed offsets between time zones can shift by an hour depending on the time of year.

Why does converting to Tokyo sometimes show a different date?

Large time zone offsets can push the converted time past midnight into the next (or previous) calendar day, which is expected and not an error.

What's the safest way to schedule a meeting across time zones?

Specify the time using one clearly labeled reference zone or UTC, or use a calendar tool that automatically converts to each participant's local time zone.

About this Time Zone Converter

Converting a time between locations means accounting for each location's offset from UTC, plus whether daylight saving time is currently active there — a detail that trips up even careful manual calculations. For a full breakdown of how time zones and DST work, see the time zones guide.

Why manual conversion goes wrong

The most common mistake is using a fixed offset (like "London is 5 hours ahead of New York") without checking whether both locations currently observe daylight saving time. Since the US and Europe switch DST on different dates each spring and fall, that "5 hour" gap is actually only correct for part of the year — during the transition weeks it's temporarily 4 hours.

Worked example

A 2:00 PM meeting in New York (Eastern Time) during standard daylight saving periods converts to 7:00 PM in London, 8:00 PM in Paris, and 11:00 PM in Dubai on the same calendar day — but converts to 6:00 AM the next day in Tokyo, since Japan's large offset pushes the equivalent time past midnight.

Best practice for scheduling

When sending a meeting invite across time zones, specify the date and time using one clearly labeled reference zone (or UTC) rather than assuming everyone will do the math correctly themselves. Calendar apps that auto-adjust to each recipient's local time zone remove this risk entirely.
