Time Tutor

A simple, practical way to learn time zone conversions rote.

Are you in New York and work with someone in London? Want to finally stop subtracting 12 when converting 24-hour time? Tired of doing math? Time Tutor was built for you.

The quiz drills 24-hour clocks, translates meetings between world cities, and lets you toggle daylight savings exactly the way your team works. Twelve customizable skins keep things fun while muscle memory does the rest.

Use the Settings page to pin your most common timezone pairs and flip DST on/off, then check the Learn page for the daylight-savings cheat sheet covering every supported city.
