Figured I might post it here for the community's perusal and comment. I wanted to simplify it while at the same time making it meaningful enough that my players would take to it quickly and want to use it. I asked myself what would a calendar look like if I wanted to make it at least somewhat similar to ours (for familiarity's sake) but it wasn't bound to the actual tradition's of Earth cultures or history. This is what I came up with.
12 months of 30 days each, which is simple enough. Rather than week-day names, each day is simply referred to by its number (the first, the second, the twentieth, etc.). Regular events are commonly referred to in a similar fashion – i.e. ‘every fifth-day’ would take place on the 5th, 15th and 25th of the month. Scheduling usually revolves around periods of 5 or 10 days, though every 15 days and every 30 days is common as well. 90-day schedules would typically be the longest as a result of Fool's Day and the four seasonal feast days. Regionally, certain days of the month have some sort of local significance and are given their own names as a result. The term 'ten-day' essentially replaces the concept of a week in common parlance, i.e. "I'll have payment for you in the next ten-day or so."
There are five days each year that occur outside of the normal schedule; they take place between months with the Summer Solstice (Summer’s Day) marking the mid-point of the year and the Winter Solstice (Winter’s Night) marking its end and beginning. The Spring Equinox traditionally represents the mid-point of planting season while the Autumnal Equinox represents the mid-point of the harvest. Finally, there is a ‘Fool’s Day’, though it is given different names and different significance throughout various regions. In some places it is regarded as a day to catch up on things neglected or a day to remember those lost, but most commonly (particularly in large urban areas) it is a day of celebration for celebration’s sake, bidding the last days of summer a final farewell. Regardless of its context, it is intended to be a day free from labor or worry.
There is no official start of the seasons though unofficially they begin at the mid-points of Calistril (Spring), Desnus (Summer), Arodus (Fall) and Neth (Winter). Like the Equinoxes and Solstices, these days are commonly treated holidays, depending where you are.
There is (deliberately) no analog to 'Leap Day' or Leap Year.
Months and seasonal feast days of the calendar year:
Abadius (January)
Calistril (February)
Pharast (March)

If you wish to further divide the day, it is most commonly broken up into four time periods: Pre-Dawn, Morning, Afternoon and Night.

A lot of this info has already been supplied by Paizo and doesn't map onto what you've written here. The Golarion calendar is pretty much the same as ours. Ex: Calistril and February both have 28 days and every 4 years include an additional day for leap year. Originally it was 12 months with 30 days each but they changed it.
You can find all of this info and its associated references here: https://pathfinderwiki.com/wiki/Absalom_Reckoning
Not to mention there is already a highly usable one available online that you can even choose the year on to fit it to your game.

Time
Like Earth, Golarion spins on its axis once roughly every 24 hours. A week has 7 days and a year has 52 weeks. To keep the calendar synchronized with the astronomical year, an extra leap day is tacked on to the second month of the year every 4 years.
Followed by a list of the names of the months and the names of the days, with their English equivalents.
