The short version: Fantastical is the most popular general calendar with solid time-zone display. Dato and Dot are the best menu-bar calendar replacements. Vimcal is the strongest calendar-first pick with a built-in overlap view. Amie is the most AI-forward, at a subscription cost. Itsycal and MeetingBar are excellent free tools for a different job entirely. Atlas is the one built specifically to find a distributed team's overlap and book the meeting, for $4.99 once.
Mac calendar and menu-bar apps split into three real camps: ones that display the time somewhere else, ones that want to replace your whole calendar, and the one built to solve cross-timezone team scheduling specifically. Knowing which camp an app is in tells you almost everything you need to know before you read a single feature list.
Fantastical: the popular all-rounder
Fantastical is one of the most widely used Mac calendar apps, with natural-language event creation and configurable time-zone displays. It has a free tier and paid plans from around $4.75/month. It's a genuinely excellent full calendar replacement, but its time-zone tools are a feature inside a general calendar, not a dedicated team-overlap scheduler.
Best for: calendar-first users who want a mature, full-featured calendar app and solid time-zone display alongside everything else.
Dato: the customisable menu-bar clock and calendar
Dato is a highly customisable menu-bar clock, calendar and world-time display, a $14 one-time purchase with no subscription. It shows multiple clocks and lets you tailor exactly what appears in the menu bar, but it has no meeting-suggestion or scheduling-assist features of its own.
Best for: users who want a heavily customised menu-bar display and will do the actual scheduling elsewhere.
Vimcal: the calendar with a built-in overlap view
Vimcal is a full calendar app with a "Time Travel" view for visualising a team's time-zone overlap, at $15/month or $120/year. Of everything on this list besides Atlas, it comes closest to solving the same problem, just from inside a full paid calendar replacement rather than a focused $4.99 tool.
Best for: teams and EAs who want to replace their whole calendar app and are happy paying a subscription for overlap scheduling built in.
Dot: the menu-bar calendar for solo power users
Dot condenses your entire calendar, events, search and meeting joining, into the menu bar, plus two extra inline time zones, for $14.99 one-time. It's a strong all-in-one for a single user, but its time-zone support tops out at two personal reference clocks, not a team view.
Best for: solo power users who want their whole calendar workflow in the menu bar.
Amie: the AI-forward subscription suite
Amie is a polished calendar, tasks and notes app with AI meeting notes, at $10 to $30 a month. Time zones are a minor feature inside a much bigger product.
Best for: people who want one premium subscription to hold their whole schedule, tasks and notes together.
Itsycal and MeetingBar: excellent, but a different job
Both are free, open-source, and genuinely well made, but neither touches time zones at all. Itsycal is a lightweight calendar dropdown that mirrors your Mac's own Calendar app. MeetingBar shows your next meeting and joins it in one click across 50+ services. They're worth having, just not for this specific problem.
Best for: a fast personal calendar glance (Itsycal) or joining meetings quickly (MeetingBar), alongside a dedicated scheduler.
Atlas: overlap, suggestion, one-tap booking
Atlas is the only app here built around one job: pin teammates and cities on a world map, shade everyone's working hours so the overlap is visible at a glance, auto-suggest the best meeting time, and add it to your calendar in one tap, in everyone's correct local time, with daylight saving handled for you. It's private (no account, nothing leaves your Mac) and costs $4.99, once.
Best for: anyone who regularly books meetings across time zones and wants the overlap found, the moment suggested, and the event created without a converter or a mental-maths session.
If you just need to glance at a couple of other clocks, a display tool is plenty. If you want a whole new calendar app, several of these are excellent. If the actual bottleneck is finding when a distributed team can meet, only Atlas and Vimcal are built for that specifically, and Atlas does it for a fraction of the price with no subscription.
