Re: [weewx-user] Re: WeeWX Returning Moon phase as Full when it should be Waning Gibbous

Karen, It is that calculation that appeared to be 2 days out of sync with with the other sources mentioned in my original post.

Each part is 12.5% of the time (month). That applies to full moon and new moon as well.  Steeple Ian schrieb am Mittwoch, 20.

It would also not surprise me that, depending on the time of day of full moon (ie the precise point in time when the Moon is fully illuminated rather than the ill-defined period where the Moon is said to be 'full'), this delay can be seen to be exacerbated on occasions. We could of course look at changing the calculations used by WeeWX; perhaps someone might like to start by providing clear definitions of the 8 Moon phases used by WeeWX.
