Frequently Asked Questions

Why are timezone abbreviations confusing?

Many abbreviations are reused for different timezones — for example, 'CST' can refer to Central Standard Time (UTC-6), China Standard Time (UTC+8), or Cuba Standard Time (UTC-5).

Does the lookup show DST adjustments?

Yes. For timezones that observe daylight saving time, the tool shows both standard and daylight abbreviations (e.g., EST vs EDT) along with the dates when the switch occurs.

How many abbreviations are in the database?

The database includes hundreds of timezone abbreviations from around the world, covering all major and many minor timezones.
