World Clock & Time Zone Converter
Compare times across multiple cities simultaneously. The timeline view shows working hours (green), sleep hours (dark), and the current hour (blue) at a glance — making it easy to find the best time for international calls and meetings.
How to Use
Add cities using the search box below the timeline. Each row shows 24 hours for that city, colour-coded by time of day. Working hours (9am-5pm) are highlighted in green. The current hour is marked in blue across all timezones.
