World Clock
A world clock displays the current time across multiple time zones side by side so you can plan meetings, coordinate travel, and schedule shifts across a distributed team. Remote-first companies use it to pick meeting times that respect everyone's working hours, travelers to track home and destination times, and operations teams to monitor coverage across regions. The tool accounts for daylight saving transitions, which shift relative offsets twice a year. It removes the mental math of subtracting hours and the embarrassing mistakes that come with it. The clock reads the current UTC time, then converts it to each selected city's local time using the IANA time zone database. Daylight saving transitions are applied automatically based on each zone's rules, so a city that observes DST shifts its offset on the correct date without user intervention. The display updates every second so the times stay live, and each city is shown alongside its UTC offset for quick cross-reference. Optional 12-hour and 24-hour formats accommodate regional preferences.
