8 Degree Availability Calendar

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 84% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

The newest reviews say the plugin stopped working and looks abandoned, with theme conflicts and dates displaying wrong, while the older ones praised the calendar and the help they got from the developer.

   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.

   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.
