Date Calculator

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 · 100% 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.

Reviewers like how simple and useful it is, though a couple flag that custom date formats don't work with the date_add shortcode, with one posting a manual code fix.

   To use this plugin with custom date format on date_add and date_sub here is how to easily fix it. Go to the Plugins -> Plugin Editor then select Date Calculator. You are now on editable date-calculator.php FOR date_add There you need to find line 203 and replace with this code: $datecalc = date($format, mktime(0, 0, 0, date(“m”)+$month, date(“d”)+$day, date(“Y”)+$year)); FOR date_sub Find line 244 and replace with this code: $datecalc = date($format, mktime(0, 0, 0, date(“m”)-$month, date(“d”)-$day, date(“Y”)-$year)); Now you can use custom date format.

   the only one reason I dl this plugin is automatic display for a future date based on today, but too bad there’s a format issue for date_add short code, please fix this in the next update, thank you, good job. This topic was modified 7 years, 5 months ago by tojekotewo.

   Great plugin, just noticed that the date format doesn’t work when paired with date_add.
