Spiffy 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 · 78% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Modeled within the band wp.org reports; tightens as we track daily.

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.

   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.

   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

   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.
