Frequently Asked Questions
How do I schedule a meeting across time zones?
Enter the meeting time in your zone, then convert to each participant's zone to find a slot that works for everyone. The live world clock helps you see current times at a glance.
Does it handle daylight saving time?
Yes. It uses your device's IANA time-zone database, which accounts for daylight saving rules for each region and date.
What is UTC?
Coordinated Universal Time is the global time standard that doesn't observe daylight saving. Time zones are defined as offsets from UTC (for example, IST is UTC+5:30).
