Share across your devices and with others. When you’re signed in to iCloud, your calendars are kept up to date on all your Macs, iOS devices, iPadOS devices, and Apple Watch. You can also share calendars with other iCloud users.
Tip: If you add a location to an event, Calendar shows you a map, estimated travel time and time to leave, and even the weather forecast.
