Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Calendar.online is a browser-based shared calendar for individuals, families, teams, companies, schools, clubs, and other groups. Its core model combines shared calendars, configurable access links, sub-calendars, booking pages, reminders, event views, imports, exports, and website embedding. Official apps are available for iOS, Android, and macOS, while the web version provides the main calendar experience. It suits small teams that need a shared scheduling space and embeddable booking calendars without committing to a paid plan immediately.
The free Basic plan includes up to 6 sub-calendars, 3 access links, unlimited users, 1 booking product or link, Android and iOS apps, and 1 year of historical data. Plus costs $6.90 per calendar per month with monthly billing, or $5.52 per calendar per month with annual billing. It raises the limits to 20 sub-calendars, 10 access links, 5 booking products or links, and 5 years of historical data, while adding email reminders. Premium costs $14.90 per calendar per month monthly, or $11.92 annually, and adds unlimited sub-calendars, access links, booking products, and historical data, plus SMS reminders and an API interface.
Calendar.online connects with Microsoft Outlook, Google Calendar, Apple Calendar, Thunderbird, iCalendar, Make.com, and WordPress. It supports iCalendar imports and iCalendar or Excel exports, along with configurable read/write permissions and automatic synchronization between its web version and official apps. External-calendar synchronization is one-way, so teams needing true bidirectional updates across outside calendars should consider another option. Choose Calendar.online for shared scheduling, booking links, and website embedding; choose a different calendar when two-way external sync is central to the workflow.
