Biggest opportunity: Swap “block” and “calendar” for “color coded” and “responsive calendar”. “block” isn't earning its slot: you're not in the first 24 results for its own search. “color coded” sits at #4 untagged, close enough for a declared tag to move it up. “calendar” isn't earning its slot: you're not in the first 24 results for its own search. “responsive calendar” sits at #11 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 2K of 209.6K lifetime downloads are still running, below its category: the median Blocks plugin keeps 2.1%, across 1,581 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Blocks plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 4 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

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.

What to do about it

Great in design and function. Has almost everything… 😉Unfortunately, I’m still missing a multiple ICS import function.Then it would be perfect. Is this function planned for a future update…? atallen

A great calendar. It fulfills all my requirements. Great personal support too to solve “clashing” problems with other plugins.

I cannot say enough about this plugin! The support is soo amazing!! This plugin has solved many problems for many of my different client websites. The support is fast, personal, feels like you’re working with a friend.

To replace a recurring event for one day. Simply create an event in the same category and date of the one being replaced and set it to ‘hide’. All events in the category selected will be hidden for the date(s) selected. I put that first because apart from the fact that I couldn’t figure out how to suspend an event for a day I loved Spiffy Calendar. I love being able to set different colours to different categories and to add information (available on mouse hover) including pictures and web addresses. Thanks Spiffy team. Thankyou support for responding so quickly too. Audrey

Hello Spiffy-Devs, I just want to say thank you for this very useful piece of software. Spiffy calendar is compared to other solutions perfect for my little blog. It’s not overloaded and offers good customization. The support is really great and helpful too. Kind regards Andre

This calendar has a very important function I was looking for. The widget shows the event when you hover the mouse over the day

I use this plugin for a few years with happiness. It is ideal for indicating birthdays on a family site. I recently had a slight problem with encoding in the database, and the author of the plugin was very reactive: he quickly found and published a patch. Thank you so much!

In the past two weeks, I’ve tested about a dozen event calendar plugins. When I landed on Spiffy Calendar and began using it, I knew that the authors were experienced and understood how to create a user-friendly, simple, elegant program. It works like a charm. The ONLY (tiny) issue I have is that it took me a minute or two to discover where to find the URL for the calendar. It wasn’t self-evident. It should be. Yes, it’s in the documentation — where I eventually looked. I might also suggest that Spiffy make it easier to donate. I’d love to send them a donation — even though I don’t need any of the add-ons, but I have not found a link to do that. Thanks for a great plugin. Much appreciated. Have a great 2019.
