Timezone App is the easiest way to compare times across cities and schedule meetings across timezones.

See the time across multiple cities at a glance — and find the perfect meeting time for everyone, no matter where they are.

Whether you're coordinating a standup across three continents or just figuring out if it's too late to call your friend in Tokyo, we've got you covered. The mobile-friendly design means you can check times and schedule meetings from anywhere.

• Side-by-side time comparison — view current times in multiple cities on a single screen.
• Shareable meeting links — select a time range and share a link that shows the proposed window and timezones.
• Calendar integration — connect Google Calendar or Outlook to overlay your events on the timeline and avoid double-booking.
• Automatic DST handling — powered by the IANA timezone database, so displayed times adjust automatically when clocks change.
• Full mobile support — intentionally designed for phones and tablets, so you can also work on-the-go.
• No account required — all core features work immediately. Sign in only if you want to connect a calendar.
• Completely free — built with love to help people work better together.

We take your privacy seriously. Your calendar data is processed entirely in your browser and never touches our servers — so your data stays yours.

Start by adding the cities or time zones you work with. The app displays a visual timeline where each hour is color-coded to show business hours, evening, and overnight periods at a glance.

Drag across the timeline to select a time range and the app highlights the corresponding local times in every city, making it easy to find a window that works for everyone. You can then copy a shareable link so recipients see the proposed time in their own zone.

Optionally, connect a Google or Outlook calendar. Your events overlay directly on the timeline, letting you spot conflicts before you send an invite.

Timezone App is designed to keep your data in your hands. When you connect a calendar, events are fetched using a short-lived token and rendered entirely in your browser. No calendar data is sent to or stored on our servers.

Without a calendar connection, the app stores only your selected cities in local storage — nothing leaves your device. For full details, see our Privacy Policy.

Do I need an account to use Timezone App?

No. All core features — time comparison, timezone conversion, and shareable meeting links — work without creating an account. You only need to sign in if you want to connect a Google or Outlook calendar.

Is Timezone App free?

Yes. Timezone App is completely free to use with no paid tiers, usage limits, or ads.

How does the calendar integration work?

When you connect a Google or Outlook calendar, Timezone App requests read-only access to your events. Events are fetched and displayed entirely in your browser so you can spot scheduling conflicts. No calendar data is stored on our servers.

Does it handle daylight saving time?

Yes. Timezone App uses the IANA timezone database (the same source used by operating systems and programming languages), so displayed times automatically adjust when clocks change for daylight saving time.

Can I share a proposed meeting time?

Yes. Select a time range on the timeline and copy the generated link. When recipients open it, they see the proposed window converted to their own local time.
