World Clock
Track current time across selected cities with search, 12/24-hour mode, seconds, copy, reset, clear, and fullscreen.
Compare selected cities at one instant
Add cities to the list and remove rows you no longer need. Every row is calculated for the same current instant, using that city's IANA time zone. The date can differ across rows near midnight.
Add New York, London, and Tokyo. If New York shows Monday evening, Tokyo may already show Tuesday morning. The difference reflects each zone's offset on the current date, including runtime daylight-saving rules.
Clock versus conversion
World Clock follows now. Time Zone Converter accepts a chosen date and wall time, while Meeting Planner checks one proposed meeting across several zones. This page depends on the device clock and browser time-zone database. Its city list is not an account-synced schedule.
If current times are not enough and you need to choose a future meeting slot, use the time zone meeting planner to compare dates, duration, and local work-hour windows.
