The best world clock apps for Mac

The Mac's menu bar shows one time. If you work across time zones, here are the ways to see more.

The options

Built in, free: the World Clock widget (right-click the desktop → Edit Widgets → Clock) and the Clock app's World Clock tab on macOS Ventura and later.
In the menu bar: The Clock ($4.99 on the Mac App Store) shows several cities from the menu bar. Many smaller menu bar clocks list a few cities for a dollar or two.
On your desktop: Ghanta Ghar, from Spritefolk. A pixel clock tower with your time on top and two cities below, plus a planner that finds a meeting time that works for everyone.

Tips

Name cities, not zones: "Bengaluru" is easier to read than "IST", and it handles daylight saving for you.
For meetings, compare working hours, not just times.

Step by step: show multiple time zones on your Mac desktop.
