Calendar plugins split into two different jobs: publishing events for people to attend and booking appointments for people to buy. We have deployed both kinds for hundreds of clients, and this list is sorted so you can pick the tool that matches the job.
How we chose
- Clear fit: events calendar, appointment booking or both.
- Recurring events and time-zone handling, where most calendar plugins stumble.
- Payment and ticketing options when the calendar drives revenue.
- Front-end quality without heavy custom styling.
- Honest free tiers and sane add-on economics.
Verdict
For public event listings, The Events Calendar is the safe default and Modern Events Calendar is the pick when design variety matters. For appointment booking, Amelia is the most complete, Simply Schedule Appointments is the easiest to set up, and Bookly suits multi-staff service businesses. If you just need a lightweight calendar and nothing else, Sugar Calendar stays out of your way.
Whatever you pick, treat booking plugins like any payment-connected software: keep them updated and test the booking flow after every major release.
