Frequently Asked Questions
Common questions about ACS Business Calendar
One. A calendar rejects a second event on a date that already has one, on both the add and the edit screen. If you need several things on the same day, create a second calendar and place both shortcodes on the page.
Only events with a capacity above zero get a mark. The plugin counts the confirmed bookings of the event and compares them with the capacity: a cross when nothing is left, a triangle when 30% or less of the capacity remains (always at least one place), and a circled mark otherwise. An event with a capacity of 0 accepts bookings without a limit and shows no mark.
Rokuyou depends on the Japanese lunisolar calendar, so it cannot be worked out from the Gregorian date alone. The plugin ships a table of the first day of every lunar month from 22 November 2014 to 23 February 2066 and derives the rokuyou from it. Dates outside that range simply show no rokuyou rather than a wrong one.
Japanese public holidays from 2016 to 2099, worked out from the Act on National Holidays: the fixed dates, the Happy Monday holidays, the two equinoxes, the substitute holiday after a holiday that falls on a Sunday, and the weekday sandwiched between two holidays. The years whose dates were moved by special legislation are included as bundled overrides. Nothing is fetched from a holiday API.
No. There is no outbound HTTP request anywhere in the code, no tracking script, no external font and no remote update check. The only e-mails sent are the booking confirmation to the visitor and the notification to the address configured on the calendar, both through wp_mail().
Deleting the plugin from the Plugins screen drops both of its tables, removes its option and deletes the calendar posts it created. Deactivating the plugin changes nothing, so you can deactivate it safely while you test something else.
Yes. The interface is in English and the source strings are in English, so translations can be contributed at translate.wordpress.org. Rokuyou and the Japanese holiday marks can be turned off per calendar if they are not relevant to you.
