In their own words
Fastmail Calendar
Fastmail Calendar is an online calendar integrated with Fastmail email, available on web, Linux, macOS, Windows, Android and iOS. It supports two-way calendar sync and shared calendars, including business plans with sharing and administrative controls. Users can bring in calendars from Google, iCloud and elsewhere, search instantly, and organize events with drag-and-drop editing. It can show schedules in other time zones, compare emailed event updates with earlier versions, and manage calendars offline in its apps; changes sync when the device is back online. Fastmail documents calendar access through CalDAV and JMAP APIs for account data more broadly. The service is paid, has a 30-day trial and does not list a free plan. Options include Basic at $4 a month, Individual at $6 a month, Standard at $6 a month, Duo at $10 a month, Professional at $10 a month and Family at $14 a month. Longer billing terms have separately listed rates. Fastmail was founded in 1999 and is headquartered in Melbourne, Australia.
