Calendar

75 Quality Score

Active Installs

16/30

4,000 active installs is modest, placing this well below category leaders like The Events Calendar at 700,000 installs, which signals limited mainstream adoption.

Update Freshness

25/25

The plugin shows a recent update timestamp and is tested against WordPress 6.9.4, suggesting the developer is actively maintaining compatibility.

User Rating

11/15

A score of 74 from 24 raters is decent but the small sample size means the average could shift meaningfully with a handful of new reviews.

Support Health

8/15

Zero support threads and zero resolved tickets is a red flag, indicating either very few users or that the developer has not engaged with the WordPress.org support forum.

WP Compatibility

15/15

Tested with the latest WordPress release and meeting the required version of 6.2.4, so compatibility should not be a concern for current sites.

What It Does

Calendar is a lightweight WordPress plugin that lets site owners create and publish events, appointments, and dates for visitors to view. It provides a straightforward calendar interface without the complexity of ticketing or booking workflows. The plugin focuses on displaying scheduled items rather than handling reservations or payments.

Who It's For

This plugin fits small organizations and individuals who need a basic, low-maintenance way to publish upcoming events or availability on their WordPress site. It works well for community groups, clubs, freelancers showing availability, or any site that just needs a public-facing calendar of dates.

Who Should Skip It

Anyone needing booking, ticketing, payments, recurring events, or attendee management should avoid this plugin, as it lacks those features. Larger sites or businesses requiring reliable support channels will also want to look elsewhere given the zero resolved support threads.

The Bottom Line

Calendar earns a 74.73 quality score and handles the basics of event display without bloat, but its lack of support activity and small install base make it a cautious choice. It is reasonable for very simple needs but anyone needing growth features or reliable developer help should compare alternatives first.
