Biggest opportunity: “appointments booking calendar”, “availability calendar” and “book availability” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.

of downloads still active
At least 200 of 29.3K lifetime downloads are still running, in line with its category: the median Booking & Events plugin keeps 0.8%, across 940 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Booking & Events plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
High removal-risk signals
75/100Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.
- Long abandoned. No update in 8+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 4.9.35, well behind 6.8.
- Reviews souring. Recent reviews read meaningfully worse than older ones, an early sign of decline.

How it's tracked →Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.
Not enough tracked days yet to call a direction. Momentum needs at least three keywords measured a week or more apart.
wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

I’ve had this plugin in use for a good three years…now suddenly, it no longer displays at all on my website and the admin section in the plugin doesn’t load. I see no updates for over two years, so I’m guessing this one has been abandoned. Skip it. This topic was modified 5 years, 8 months ago by stsorrell64.

Simple calendar, does not work with all themes, calendar display of days gets squashed to one side, With other themes that it does display properly, it does not display what is selected in the admin calendar accurately. It will skip displaying days that are selected as unavailable in the admin.

Thank you so much for all your help making some minor style changes to the plugin! This plugin is EXACTLY what I was looking for to show booked dates for a photographers website. It was so easy to deal with you! Thank you once again for all your support.
Read on wp.org ↗ - ★★★★★ Big Frank9.0y ago
This could have been just the simple availability calendar I was looking for but when I installed it it clearly had serious issues: the month/year drop-lists were one underneath the other, not side by side as in the screenshots the Next/Prev buttons weren’t there at all you’re limited to one calendar, would have been great to have the option for multiples in a premium version I had no option but to uninstall it. It’s clear this hasn’t had any support from the developers for a very long time. Shame, might have been a useful plugin. These guys also do templates but if you’re using a rotten carrot you’re not going to get the donkey to follow you, even if it’s free. This topic was modified 8 years, 8 months ago by Big Frank.

A very good plugin to show a calendar on its website. The support was very useful to help me to install it 🙂

Not working with my theme (soho hotel) (each second or third date is closed), but beside that I don’t see the point of this plugin. There is only ONE calendar? You cannot add more.
