World Clock — Free Online Tool
Scheduling a call across continents is easier when you can see every city's clock at once. This world clock shows live, second-by-second time for UTC, India (Asia/Kolkata), New York, Los Angeles, London, Paris, Tokyo and Sydney, using the time-zone database built into your browser, so daylight-saving changes are handled for you. Indian Standard Time is UTC+5:30 all year and has no daylight saving, which means the gap between India and the US or UK changes twice a year: for example IST is 10.5 hours ahead of New York in winter but only 9.5 hours ahead once New York moves to daylight time, so a live view avoids mistakes. Freelancers, remote developers, students applying for foreign universities, NRIs calling family and customer support teams can use it to find a sensible meeting slot or to know whether a client is likely to be awake. It also helps when you read timestamps in logs or server dashboards that use UTC. The display refreshes every second and needs no sign-up. It does not convert a specific future time between zones, so for that, note the current offset shown here and apply it to your planned time.
