sometimes my birthday falls on thanksgiving too

cant keep track of how often but seems like every 6-7 years. I suspect the mzls is the same way if I looked at the calendar far enuf ahead.
This is going to sound complicated, but it's not. Because of the way Thanksgiving is determined (4th Thursday of November), and the way the openers of gun and MZ season are linked to Thanksgiving (Saturday before, and third Saturday before, respectively), the range of dates that MZ can open is limited to 7. The earliest MZ can open is Nov. 3 and the latest is Nov. 9.
And because Nov. 1st falls one day later in the week each year, opening of MZ falls one day earlier each year (except after a Leap Year, when it jumps 2 days earlier). The transition point from earliest to latest is when Nov. 1st moves from Thursday to Friday. So MZ opener cycles from Nov. 9th down to Nov. 3 and then jumps back up to Nov. 9 in an endless repetitive circle. Looking at the date of MZ opener by year looks like this:
2013: Nov. 9
2014: Nov. 8
2015: Nov. 7
Leap year (skip two days)
2016: Nov. 5
2017: Nov. 4
2018: Nov. 3
2019: Nov. 9
Leap Year (skip two days)
2020: Nov. 7
2021: Nov. 6
etc.
wonder who decided how many days in a year then invented leap year lol
Julius Caesar. He implemented the Julian Calendar in 46 BC, which establish a year as being 365.25 days, which creates the extra calendar day (Leap Year) every four years.
Of course, no one arbitrarily established the number of days in a year. A year is how long it takes the Earth to circle the Sun. That just happens to take a little over 365 days.
