There are a few websites that tell you what day of the week March 26th was for the last few years. But I want to know how many times March 26th has EVER been on a Monday, at least for the last 100 years.
Anyone know where I could find out?

If you’ll take the lower limit as 1/1/1900 then Excel will tell you there have been 17 Monday 26th Marchs

iCal on Mac, or whatever the equivalent program on Windows is, will tell you, provided you don’t mind clicking a lot. It’s fallen on a Monday 3 times since Y2K.
any date is on a given day of the week approximately one out of seven years so March 26 has been on a Monday either 14 or 15 times in the last 100 years. From now back to 1901, the calendar repeats (for days of the week though not holidays like Easter) exactly every 28 years. It gets a bit more complicated before that since 1900 (and 1800 and 1700) were not Leap years.
It’s also a bit complicated depending on exactly where you want to know the date. Most countries now use the Gregorian calendar at least for civil and commercial purposes, but that was not always true. Russia for example didn’t adopt it until after the Communist Revolution in 1917 (I think they didn’t adopt it until the 1920s. Greece and Turkey adopted it even later. The UK and its colonies including what became the US adopted it in 1752 or 3 (and at the same time changed New Year’s Day from March 25th to Jan 1).
Nevertheless, in any span of time March 26th was a Monday about every 7 years and the longest stretch you can go without a Monday March 26th would be ten years. The day of the week for any given day moves forward through the weekdays one day at a time skipping a day in leap years so you could have for March 26th in consecutive years:
M T W F Sa Su T W Th Sa Su M
where the normal next Monday date was skipped after 5 years.
Note that there is an error in Excel’s Weekday function. It gives
Weekday(2/28/1900) = 3 meaning Tuesday
Weekday(2/29/1900) = 4
Weekday(3/1/1900) = 5
But there was no Feb 29th in 1900 under the Gregorian calendar. This error doesn’t affect this particular problem since Excel’s function is good for 3/1/1900 on but it’s off by a day before then.
(bolding mine)
Well, now that it looks like you’ve been given a factual answer to that particular question… the next (IMHO) obvious question is, why do you want to know that?
AFAIK February 30 has never landed on a Wednesday in any national calendar in modern times, but it did land on a Tuesday in 1712.
Any given date is going to appear approximately one year in seven on average. Over the long run that will be exact. Over the long run, the calendar should cycle, assuming the calendar is not changed, it will cycle every 28,000 years and every day will appear exactly one year in 7. But in the current calendar, it cycles every 400 years and not every day appears the same number. Going back to the formation of the Gregorian calendar, I know that the 13th day of months comes on a Friday more often than on any other day. I don’t know how often March 26th falls on a Monday, nor finding out how many except by counting it over 400 years.
The reason for the 28,000 year cycle is that leap year is supposed to be omitted in every year divisible by 4000 as a minor correction to the current definition. Any further correction beyond that would depend on the speed at which the length of the day increases.
I like the way OldGuy thinks.
I can’t remember the name (and SD thread) and similar examples for seemingly absurd and uncountable problems that, as an employment test or otherwise, are more or less solvable in your head using just a few givens.
It trains you not to panic and to use your mind, or what you can get at of it. Where do they teach this stuff?
ETA: also the thinking of Hari Seldon, as I now see, and other guys, all of whom are not me.
In the Breakfast Club (1985), John Hughes gives us an exact date for the detention- saturday march 24th 1984. At the end of the film the characters ponder whether, when they return to school on Monday, they will have the courage to be seen interacting with each other in front of their respective cliques. We never see whether this happens, but the date of this return to school would have been Monday march 26th 1984.
On the night of Sunday march 25th, 2012, I became convinced that something epic would happen at a local high school the next day. I hadn’t seen The Breakfast Club since I was 11 at that time. The next day I trespassed at the local high school at the end of the school day, walking through the hallways posing as a student, observing different cliques and their interactions. It was fun, especially the emo Asian group with spiked hair.
Over a year later I caught the Breakfast Club on cable and realized I had infiltrated a high school on the exact date and day of the week as the epic Breakfast Club returns to school day. Since the film came out, march 26th, I now know, has only been on a Monday 4 times, one of them when I was only a little kid and one of them when I was a sophomore in high school. The odds of me trespassing at a high school on a Monday march 26th were very low.
Just more evidence that I’m god, the one who created high school, cliques, childhood, and everything else in the universe.
Also, I recently discovered that a kid in the grade above me in high school was named John Hughes.
As opposed to what? Is it not pretty self-evident that any given date will be a Monday one-seventh of the time in the long run?
There have been 290 Monday March 26ths since year 1 AD according to cal.
value=0; for i in {1..2013}; do if cal 3 $i | grep -ci "^25 26"; then value=`expr $value + 1`; fi; done; echo $value
2014 / 7 = 287.7, so that’s pretty close to even distribution.

So I’m thinking maybe you’re a teenager? Or young 20’s…
But this:
Are you only 12 or 13 years old? Or you were you 11 when The Breakfast Club came out?
I’m trying to jive this with the sentence in your post:
You’re either young and confused, or a bit crazy and need some help…
Oh shit, I messed that sentence up.
I meant at that time, I hadn’t seen the movie since Many years before when I was 11. I was 27 when I trespassed.
The universe is 13.798 billion (plus or minus 37 million) years old. One year in seven has its March 26th on Monday. So there have been approximately 1.971 billion (plus or minus 5 million) Monday, March the 26ths.
That’s a lot of Breakfast Clubs.
As opposed to me, as I implied in my ETA…
It’s the very “self-evident-ness” of that fact that I mentioned, and it’s subsequences that are impressive.
So what are those kind of problems/solutions called?
Not exactly. The fact that it cycles every 400 years and various effects to due maintaining integral days and such cause some day-day of the week combination to be more or less common than others. Within a 400 year cycle, the total number of times the firsts of the months appear on a given day of the week ranges from 684 to 688. (Monday is the most common, which strangely causes the 13th of the month to occur most often on a Friday.)
“Self-evident” is a bit strong of phrase for something that is approximately true.
Mondays, and Marches, are not nearly as old as the human race, let alone the universe.
