Time Zones & Daylight Saving

Which of your cities are on daylight saving time right now, when each will next change its clocks, and a reference table for the abbreviations you meet in emails and schedules. The converter and meeting planner live on the home page.

Time zone abbreviations

Abbreviations are ambiguous — "CST" is used in both North America and China, and "IST" in India, Ireland and Israel. Prefer UTC offsets or IANA zone names (like Europe/Berlin) when precision matters.
