About whattimewillitbein.com
whattimewillitbein.com is a free timezone calculator and future time converter. It answers the question remote teams, travelers, and internationally-minded people ask dozens of times a week: "What time will it be there when it's this time here?"
The tool was built because existing converters were cluttered, slow, or gave wrong answers around Daylight Saving Time transitions. This one is fast, DST-accurate, and generates a shareable link for every conversion — so you can send a colleague exactly what time to join a call, with no back-and-forth.
It supports 196+ cities across every continent, with timezone data sourced from the IANA timezone database — the same source used by operating systems, browsers, and programming languages worldwide.
