Lisbon is 6 hours ahead of you today.

You share 2 hours a day.

Every call you will ever have with Lisbon lives in the lit column. On both sides of it, one of you is asleep.

What a usable overlap costs

To share 4 hours, you start at 07:00, or they work until 19:00. Somebody pays, and the only question is who.

Every weekday of 2026

For 20 weekdays a year the gap narrows and you get 3 hours instead of 2 — 9–27 March and 26–30 October. You change your clocks on different dates. Nobody scheduled those hours; they arrive on their own.
