Please help me to assign the correct CalanderDay numbers to the following dates/events, so my NPC mod will handle date-specific content at the right times for holiday observances. My understanding is that the game starts on Mirtul (May) 1st, making that CalanderDay1. If not, please correct me.
What I have so far:
Mirtul/May 1 - Greengrass - CalanderDay1
kythorn/June - Summer Solstice - CalanderDay50
Eleasis/August 1 - Midsummer - CalanderDay91
Eleasis/August 2 - Shieldmeet - CalanderDay92
Eleint/September 21 - Autumnal Equinox - CalanderDay142
Marpenoth/October 1 - Highharvestide - CalanderDay151
nightal/December 1 - Feast of the Moon - CalanderDay211
Nightal/December 20? - Winter Solstice - CalanderDay233
Alturiak/February 1 - Midwinter - CalanderDay271
Ches/March 19 - Spring Equinox - CalanderDay 319
Thanks in advance for any help! Shieldmeet might complicate things by making each CalanderDay number after it higher by one, but I'm not sure about that. I'm guessing that the first days of the first four months in the game are 1, 31, 61, and 91. If Shieldmeet offsets the numbers after it, then the first days of the rest of the year would be 122, 152, 182, 212, 242, 272, 302, and 332. These dates are significant in my NPC's life, as they are the nights of the full moon.
