Meridian

London and Sydney meeting times

Where the working days of London and Sydney overlap, and when daylight saving moves it.

    Clock change heads-up

    One email a week before the clocks change in your cities, with the new gaps. Nothing else.

    Calling between London and Sydney

    In January Sydney is 11 h ahead of London; in July Sydney is 9 h ahead of London.

    With both sides working 9:00 to 17:00 there is no hour when both are at work. The kindest slot is 09:00–11:00 in London, which is 20:00–22:00 in Sydney, when both are awake and one side is at work.

    Watch the clock changes. London and Sydney don't change on the same day, so in 2027 the gap is 10 h instead of 11 h or 9 h from 28 Mar to 3 Apr and from 3 Oct to 30 Oct. Meetings booked by habit land an hour off in those weeks.

    Questions

    Does it handle daylight saving time?

    Yes. Every time is worked out for the date you pick, using your browser's own time zone rules. Pick a date in March or October and the rings move to match, including the odd weeks when Europe and North America change on different Sundays.

    Can I set different working hours for each person?

    Tap anyone's row to set their hours, rename them or make them the home city. Night shifts that run past midnight work too.

    What if there's no time when everyone is at work?

    Meridian says so, then finds the closest thing: a stretch when everyone is at least awake, with as many people at work as possible.

    How do I send the time to everyone?

    Copy times gives you one line with the time in every city, ready to paste into a chat or invite. Add to calendar downloads an invite file, and Share link opens the same dial on someone else's phone.

    Do I need an account?
