When can I ring?

Pick where you are and where they are. You will see their day beside yours, the hours when you are both awake, and a good time to ring.

Choose both places to see the hours.

Waking hours

We assume people are up from 7:00 to 22:00, and that 9:00 to 21:00 is a fair time for a call. Change it if they keep other hours.

City pairs

Pages for pairs of cities people often ring between, with the gap through the year and the dates the clocks change.

What this page does with your choices

Everything is worked out in your browser, from the time-zone data it already has. The two places go into the address, as short ids, so you can keep the link. Nothing is sent to us, and we never ask your browser where you are. If your device’s time zone matches a place in the list, we start from it.

Sunli will keep a clock like this for each person in your orbit. It is not ready yet.

Where things stand

Sunli is not ready yet. The design is finished and the first version is being built.

There is no app to download today and no list to join. When there is a way to hear from us, it will be on this page.
