What it does

Use calendar sets to switch which work or personal calendars are visible, create an event with natural-language input, or invite attendees and track responses. The page also lists time-zone views, location alerts, and meeting integrations. It offers a free download and says no account is required; the FAQ refers to subscriptions, so check the current App Store offer for specific features. See the official Calendar 366 page.
