I designed a barbaric calendar that I use to keep track of everything I do and my appointments.

Below are 12 special dates that I use every year over and over. It's close enough for me.

Winter

3rd Week: Jan 5th

7th Week: Feb 2nd

11th Week: March 2nd

Spring

3rd Week: April 6th

7th Week: May 4th

11th Week: June 1st

Summer

3rd Week: July 6th

7th Week: Aug 3rd

11th Week: September 1st

Autumn (Fall)

3rd Week: October 6th

7th Week: November 3rd

11th Week: December 1st

Extracting the 12 numbers above, being Sundays and Mondays in 2014, you get the data stream "522 641 631 631".

The 10th Week of Winter will be 8 days on leap years, and so the day changes that subsequent dates fall on in the chart.

The 10th Week of Summer will be 8 days long too, every year though in this barbaric chart, and the day jumps ahead there too.

Each year the same "522 641 631 631" can be used, every year over and over again, except that the name of the day of the

week changes after the 10th Week of Summer, and then every 4 years after the 10th week of Winter too.

That's my calendar I keep in my head.

So this year I'm thinking all those dates will be Sundays until September 1st, when I switch to Mondays.

In 2015, I will still be on Mondays all year until Sept 1st, and then I'll be on Tuesdays.

In 2016 (16mod4=0=leapyear), Tuesday is Jan5th and Feb2nd, on March 2nd, I switch to Wednesdays until September 1st and

then go to Thursdays.

I stay at Thursdays through the end of 2016 and all the way thru most of 2017 until Sept 1st again, and then I go to Fridays.

In 2018, I stay with Fridays until Sept 1st, and I go to Saturdays.

(I didn't check these days out, so I hope their right)

My mom is watching a movie and they mentioned Wednesday April 14th, 1965.

So add 28 years twice and get 2021, same calendar days setup.

So 2018 end of year use saturdays.

2019 switch to sundays at sept 1st.

2020 switch on march 2nd to monday.

2020 sept 1st switch to tuesday.

2021 Use Tuesday from January thru August 31st, so let's see if the

movie is right...

522 641 631 631 April 6th should be tuesday.

Add 8 days, get April 14th, yes, it is wednesday!!!! Cool, it worked!

we're in the ninth week of spring now.

i am guessing the seasons are based on the elliptical orbit which i ignore.
