Here are the festival days of Aset for the month of the 1st of Shomu or Pachons/April. Some of these festials such as the Harvest Festival and the Festival of Aset of Pharos festivals are listed twice since they have two set dates associated with them on different calendars.
The Aset of Pharos festival is listed on the 25th of April, but a footnote in one book mentioned it may also be on April 21st so I included the date here.
