Your 8:30 AM
is their 8:00 PM.

List the week’s sessions on your own clock. The converter shows each one on the student’s clock, using each country’s daylight saving dates, and flags the sessions that land too early, too late or on another day.

Every conversion goes through UTC, using each place’s own rules for that date.

Through UTC

A time zone is a set of rules for turning Coordinated Universal Time into local clock time, including when daylight saving starts and ends. Converting your wall-clock time to UTC and then to the student’s zone, for that exact date, avoids the mistake of using a fixed number of hours all year.

The tricky weeks

The United States and Canada change clocks on different dates from Europe, and most of Asia does not change at all, so the gap between you and a student can shift by an hour for one or two weeks each spring and autumn. Southern-hemisphere places such as Sydney move the opposite way.
