What is UTC and how do timezones relate to it?▼
UTC (Coordinated Universal Time) is the global time standard. Timezones are expressed as offsets from UTC: UTC+9 (Korea/Japan), UTC-5 (US Eastern), UTC+0 (UK/GMT). UTC never changes with daylight saving time, making it ideal for storing times in databases and APIs.
What is daylight saving time (DST) and which regions use it?▼
DST shifts clocks forward by 1 hour in spring and back in fall to extend evening daylight. Most of North America and Europe observe DST. Asia (including Korea, Japan, China), most of Africa, and most of South America do not. DST dates vary by country.
How do I schedule a meeting across multiple timezones?▼
Add all participants' timezones to the converter, then adjust the time until it falls within business hours (9AM-6PM) for all. For US-Korea meetings, early morning Korea time (8-9AM KST) aligns with late afternoon US Eastern (6-7PM EST). Use UTC as the reference in calendar invites.
