Time Zones Explained: How to Convert Between Them
Booking a call with someone overseas and not sure if you'll show up an hour early — or a day off? Time zones are simple in principle but full of traps. Here's how to convert times confidently.
It all anchors to UTC
Every time zone is defined as an offset from UTC (Coordinated Universal Time) — for example UTC+1 or UTC−5. To convert between two zones, convert each to UTC first, then compare. Working through UTC removes most of the guesswork.
The daylight saving trap
Many regions shift their clocks forward in summer, and they don't all do it on the same date — so the offset between two cities can change several times a year. This is the number-one cause of missed international meetings. Always confirm the current offset, not last month's.
Convert it without the headache
Our free time zone converter shows the matching time across cities, accounting for current daylight saving. For converting durations (hours to minutes, days to hours) rather than zones, use the time converter.
Bottom line
Think in UTC offsets, double-check daylight saving (which moves on different dates worldwide), and use a converter for anything scheduled. A minute of checking beats joining a call an hour late — or a day early.
