The Trinitan Calendar
This calendar is based off of the Tembarican one, but shortens a year down to the time it takes on average for Omeria to orbit all three suns once (783 days). It keeps the same months and weekdays, but also introduced the term "thirdyear", denoting the average of 261 days Omeria spends orbiting each sun. Because of the way their pantheon is organized, this calendar starts the year during what would be the second cycle of the Tembarican year, when Omeria begins its orbit around Balos. This decision makes it a bit harder to keep it syncronized with the other calendars, something that has led to it now only being in use by trinitan worshippers.
