ZoneDay — Menu Bar Calendar and World Clock for Mac

ZoneDay puts a calendar and world clocks in the Mac menu bar. One click shows the month, the day's meetings with a Join button for video calls, and the time in every city that matters, with a slider for finding a time that works across time zones. Everything stays on the Mac.

The month, one click away

A six-week month with today filled in and a small dot under each date that has an event. Step back and forward with the arrows, jump home with Today, and click any date to see what is on it. Week numbers and the first day of the week are both a menu choice away.

Join the call from the menu bar

When an event's link, location or notes contain a Zoom, Google Meet or Microsoft Teams address, a Join button appears beside it. Calendar access is read only: ZoneDay never creates, changes or deletes an event.

Every city at a glance

Search for a city or time zone to add a clock. Each one shows the local time, the UTC offset, how many hours ahead or behind it is, a +1 or ?1 when the date differs, and a sun or moon for day and night. Daylight saving is handled for every city.

Find a time that suits everyone

Drag the slider up to twelve hours either way and every clock moves with it. One click on the copy icon puts that moment on the clipboard for your own zone and every city, one line each.

The menu bar, the way it suits

Show just the icon, the time, the day and date, the day, date and time, or a custom pattern built from date format letters, with the week number if wanted.

How it works

• Click the menu bar icon and the panel opens on the current month, with today filled in and a dot under every date that has an event.
• Click Connect Calendars once and allow access. The selected day's events are listed in time order, with a Join button wherever a Zoom, Google Meet or Teams link is found.
• Click + next to World Clocks and type a city or time zone. Each clock shows the local time, the UTC offset, how far ahead or behind it is, and a sun or moon.
• Drag the slider up to 12 hours either way, in quarter-hour steps, and every clock follows. Reset goes back to now.
• Click the copy icon to put the chosen time for every city on the clipboard, one line per city, ready to paste into an invitation.
• The ••• menu holds Menu Bar Shows, Week Numbers, First Day of Week, Show Events and Open at Login.

Opening it the first time

ZoneDay is signed and notarized by Apple, so it opens with a normal double-click. The first time Connect Calendars is clicked, macOS also asks whether ZoneDay may read your calendars.

Can it add or change events?

No. Calendar access is read only, so ZoneDay never creates, changes or deletes an event, and nothing leaves the Mac. Events are still made in the Calendar app or the calendar service itself.

Which calendars does it show?

Every calendar the Mac's Calendar app knows about, including iCloud, Google and Exchange accounts added in System Settings, Internet Accounts.

Why is there no Join button on a meeting?

ZoneDay recognises direct Zoom, Google Meet and Microsoft Teams addresses. Short links, redirect links and other video services do not get a Join button.

Does it cope with daylight saving?

Yes. Every clock follows its own city's rules, including the weeks when countries change their clocks on different dates, and the slider accounts for it too.

Which Macs does it run on?

Any Mac with Apple silicon or Intel running macOS 13 Ventura or later.
