Frequently asked questions

Because a 9 AM slot in Mumbai is useless if it falls on Diwali. Most time zone converters tell you the time but not whether the time is actually workable. We mark public holidays for 50+ countries and weekends across all 100+ cities, so you can avoid scheduling something that someone has to politely decline.

😊 Best Time (08:00–19:00 local) — normal working hours. 🥱 Marginal (19:00–22:00) — workable in a pinch but late. 💤 Unavailable (22:00–08:00) — outside reasonable hours. 🏖️ Weekend. 🗓️ Public holiday in that country.

No. There is no account, no email collection, and nothing is sent to a server. Your saved cities and presets stay in your browser via localStorage.

Most country data comes from Nager.Date, an open-source MIT-licensed dataset that aggregates official holiday lists. Countries not covered there (such as India, UAE, Saudi Arabia, Israel, Iran, Thailand, Taiwan, Malaysia, Pakistan, Sri Lanka) are hand-curated from public references. Lunar holidays (Lunar New Year, Eid, Diwali) and substitute days can shift slightly when finalized closer to the date. Always confirm important meetings with the actual attendees.

Yes. The Copy Share Link button generates a URL that encodes your selected cities, base time, and date — anyone who opens the link sees the same view. The Copy Results button gives you a plain-text summary you can paste into Slack or email. Both work without any account.

The base city is the one whose local time you are entering. If you set the slider to 14:00 with Seoul as the base, every other city shows what 14:00 KST is in their local time. Switch the base city when you want to think in a different reference frame (for example, 'what should I propose as a New York time?').

It means a country's holidays differ between states, provinces, or cantons. Some federal-level countries — Australia, Germany, Switzerland, USA, Spain — have many regional holidays. The merged list shows everything observed anywhere in that country, with a per-day badge indicating which region(s) actually observe each date.

Because of the international date line. If your meeting is 22:00 in Seoul on Monday, that's already past midnight in Pacific time — so the local date for someone in Los Angeles is Sunday or Tuesday, not Monday. We flag the day shift so you don't accidentally confuse which calendar day people are on.

We cover 100+ major business cities. If your city isn't there, find a city in the same time zone — the conversion is identical. If you'd like a specific city added (for example, your country's capital), reach out via the contact page with the city name and IANA time zone.

Yes. We use the browser's native Intl.DateTimeFormat API, which uses the IANA time zone database. This means daylight saving transitions are handled automatically for any date you pick. Two countries that look 8 hours apart in winter might be 7 hours apart in summer, and the planner reflects this when you change the meeting date.

Yes, free with no signup. The site is supported by display advertising. We do not collect personal data; your saved cities stay in your own browser. See the Privacy Policy for details.

We cover 50+ countries — most major business markets — but not every country has reliable open data. If your country is not listed, the meeting planner will still work for time-zone conversion; it just won't flag holidays. Let us know via the contact page and we'll prioritize adding it.
