Timezone Converter — Compare Times Across 400+ Cities
Stop calculating offsets in your head. Drag a slider to convert between any two timezones instantly — no math, no sign-up.
What is a timezone converter?
A timezone converter (sometimes called a time zone calculator) translates a specific time from one timezone to another. If it's 2:00 PM in San Francisco, a timezone converter tells you it's 10:00 PM in London and 6:00 AM the next day in Tokyo — without you having to remember offsets like +8 or +17.
tyme replaces mental arithmetic with a visual slider. Drag any clock to the hour you want and every other timezone shows the equivalent time instantly. Day and night indicators tell you whether that time is reasonable before you schedule anything.
