Each month is composed of four seven day weeks. If Mondenberg is tied to only one mundane world, that world’s moon’s phases occur as follows: The full moon ( 🌕 ) occurs on the last day of each month, the 28th. The third quarter moon ( 🌗 ) is on the 7th, The new moon ( 🌑 ) occurs on the 14th, and The first quarter moon ( 🌓 ) occurs on the 21st of each month. This will occur regardless of the length of day or month on the mundane world, as long as it has a notable moon which causes tides, similar to our world.
