How to convert a time between time zones without getting the day wrong.

Type a time and places to convert it, with the day it falls on there and what abbreviations like EST, IST and CST were taken to mean.

The World clock's meeting planner for London, New York and Delhi, coloured by working, waking and sleeping hours

Converting a time is adding or taking away the gap between two places; the mistakes come from the day, the abbreviations and the change of clocks.

Type it as you would say it.

Type 3pm EST to IST, 15:30 London to Tokyo, or 9am New York to Delhi and Sydney tomorrow. Places can be cities, abbreviations or time-zone names, and any town of over 15,000 people once the list has loaded. The answer gives the time and the day in each place.

Abbreviations mean more than one thing.

IST is India's time, and also Ireland's and Israel's; CST is US Central Time and China's. People often type EST all year for New York, which keeps EDT in summer. The page takes each as one place's time and says so under the answer, so type the city when you mean another.

Hours that do not happen, or happen twice.

When clocks go forward an hour is skipped, and when they go back an hour happens twice. A time in that hour is said to be skipped, and the time just after the jump is used, or to happen twice, and the first is used.
