Description Paul Worrall 2022-06-03 15:09:33 UTC
1. Configure Digital Clock=>Calendar=>Astronomical Events (enable)
2. On Astronomical Events page, ensure Lunar phases are enabled

The calendar displays an event marker on every day.  
Most of the "events" are just the state of the moon on that day, i.e. mostly "Waxing or Waning" "Gibbous or Crescent"

The calendar should display event markers only for the moon's phases i.e. New moon, First quarter, Full moon & Last quarter

Comment 1 Nate Graham 2022-06-03 18:22:14 UTC
So what's going on here is that the Astronomical Events plugin adds these as events. And the Digital Clock shows a dot for every day with an event. Since every day now has an event, every day shows a dot.

We have two options:
1. Introduce the concept of the "minor event" or "informational event" that doesn't show a dot on the day, and port the Astronomical Events plugin to use that.
2. Change the Astronomical Events plugin to have fewer events; maybe it's overkill to show an event every single day showing things like "waxing gibbous" Indeed, only showing the four primary phases might make sense.

Or we could do both.
Comment 2 Nate Graham 2022-06-03 18:24:53 UTC
Ah I see what happened. the Astronomical Events plugin simply consumes data from KHolidays, which added the intermediate phases in 52eb1561be10d21f6dba4a25dafef60c85864b48. CCing Volker who added those.

So we have a third option: find a way to filter those out in the Astronomical Events plugin.
