Convert time between any time zones worldwide. Schedule meetings across countries. Free world clock and time zone converter. No signup.
Scheduling across time zones is one of the most common remote work challenges — 9am EST is 2pm London but 10pm Tokyo, and getting it wrong means missed meetings. Our converter shows current time in any city worldwide, converts any time between zones, and helps find meeting windows that work for distributed teams.
Key time zones by city: UTC-8: Los Angeles, San Francisco, Seattle. UTC-7: Denver, Phoenix. UTC-6: Chicago, Mexico City. UTC-5: New York, Miami, Toronto. UTC-0: London (GMT, UTC in winter). UTC+1: Paris, Berlin, Rome (CET). UTC+3: Moscow, Istanbul. UTC+5:30: Mumbai, New Delhi. UTC+8: Beijing, Singapore, Hong Kong. UTC+9: Tokyo, Seoul. UTC+10: Sydney, Melbourne (AEST). UTC+12: Auckland, Fiji. Note: Daylight saving time shifts many zones by 1 hour — check for DST dates when scheduling critical meetings.
Overlap hours for common US-international pairings: US East Coast and Europe: 9am-12pm EST overlaps with 3pm-6pm CET — best window. US West Coast and Europe: nearly impossible overlap — early morning or late afternoon for one side required. US East and Asia-Pacific: 7am-9am EST = 8pm-10pm Singapore or Tokyo — end of APAC day. Global teams: accept that someone always has an inconvenient meeting — rotate the inconvenience fairly rather than always burdening one region.
Time zone conversion steps: Find UTC offset for your current location. Find UTC offset for target location. Calculate difference: New York is UTC-5, London is UTC+0 in winter, difference is 5 hours. 10am New York = 3pm London. Account for DST: clocks change at different times in different countries — US changes in March, Europe in late March, Australia in April. Simplest: use our converter which handles DST automatically.
Optimal meeting windows: US to Europe: 8-11am EST is prime — after European lunch through early afternoon. US to India: 7-9am EST = 5:30-7:30pm IST — end of India workday. US to East Asia: 8-9am EST = 9-10pm Tokyo/Seoul — very early Tokyo or very late US works. Best global standup: 8am UTC works reasonably for Americas evening, Europe morning, Asia very early morning.
Officially there are 24 standard time zones based on UTC offsets. However in practice: 38+ time zones exist because some countries use half-hour or quarter-hour offsets. India: UTC+5:30. Nepal: UTC+5:45. Iran: UTC+3:30. Afghanistan: UTC+4:30. Australia (Lord Howe): UTC+10:30. Chatham Islands (NZ): UTC+12:45. France has the most time zones of any country (12) due to overseas territories.
