Daylight Saving Meeting Mismatch Checker
Your recurring meeting looks fixed, but if your teammates' countries switch daylight saving on different dates than yours, it quietly drifts by an hour for a few weeks a year. Enter your meeting once and see exactly which weeks that happens.
Why does a fixed meeting time ever change?
Most countries that observe daylight saving time don't switch clocks on the same date. The US, for example, usually moves clocks about two to three weeks before the EU does in spring, and moves them back about one week before the EU in autumn. During those transition windows, the gap between your timezone and a teammate's timezone is briefly different from the rest of the year — even though neither of you changed anything about the meeting itself.
Does this tool store or send my data anywhere?
No. Everything runs in your browser using the timezone database built into your browser — nothing is sent to a server.
What if a teammate's country doesn't observe daylight saving at all?
That's still covered. If only one side of the meeting shifts clocks (for example, the US and India, where India does not observe daylight saving), the tool detects the resulting mismatch weeks the same way.
