How to find the best time to call
Choose your city and your partner's city, then set when each of you usually wakes up and goes to bed. The calculator lines up both days and highlights the hours you share. Tick "skip 9 to 5 work hours" if you only want times when you're both off work.
The longest shared window is marked as the best time to call, with the time shown in both cities. If you see no overlap, nudge a wake-up or bedtime and watch the bars change.
Common questions
What is a time zone overlap?
It's the part of the day when you're both awake (and, if you choose, both off work) at the same time. For couples in different time zones, these shared hours are the easiest times for a call or a video date.
Does it handle daylight saving time?
Yes. It uses your browser's built-in time zone data for today's date, so clocks that have sprung forward or fallen back are already counted. Overlap can shift by an hour around daylight saving changes, so check again then.
What if we have no overlap at all?
With very large gaps (for example, the US and Australia or Southeast Asia), normal waking hours may not overlap. Try moving one wake-up or bedtime by an hour or two to see what opens up, or plan one longer weekend call when neither of you has work.
Why are the times shown on my clock?
The bars follow the first person's day, from midnight to midnight. Each suggested call time is shown in both cities, so you can each read it in your own time.
How do long-distance couples deal with time differences?
Many couples pick one or two regular call windows from their overlap, keep a shared calendar of visits, and send short messages or photos outside those hours, so the other person wakes up to something from you.
Is this tool free?
Yes. There's no signup and nothing to install. Your choices are saved in the page address, so you can bookmark it or send it to your partner.
