Time Difference & Best Time to Call: Gulf, Egypt and Travel Destinations

See the hour difference between your city and a destination on any date (daylight saving included), and the hours when both sides are awake or at work for a call. It runs on the time-zone database built into your browser.

We do not hardcode any offset. Your browser computes everything from the IANA time-zone database, so results follow daylight saving in Europe, the Americas and Egypt automatically.

How it works

• For the date you pick, we ask the browser (Intl.DateTimeFormat API) for the local time in each city.
• Difference = the other city's UTC offset − your city's UTC offset on that day.
• We list the 24 hours of your day and highlight those where both clocks fall inside your chosen range (default 9 am to 9 pm; change it).

Traveller tip

Change the date to your travel day: the gap with London or New York shifts by an hour between summer and winter, while the Gulf states do not use daylight saving.

Sources

• IANA Time Zone Database — the source browsers rely on

FAQ

Does it handle daylight saving?

Yes. The browser applies each zone's daylight-saving rules for the chosen date. Pick your travel date to get the right gap.

Why might another site show a different result?

Some sites hardcode a fixed gap and miss changes. Ours uses the IANA database on your device; update your browser if it is very old.

Do you save my choices?

No. Everything runs in your browser and nothing is saved.
