How does one change the year then?
First, you create the universe. Then you build a new year of the calendar.
Then you argue.

#42Can someone ELI5?
It took me a while, but I think I have it: choose a month of the year in the blue table and read only the column pertaining to that month. The column has seven days within it and the first day in the column matches the first day of that month; then, increment each day and date until reaching the maximum for the month and proceed to the next month in its matching column. Never move right to left in the blue month table as if moving through a standard calendar's format; only loop through the column for the current month from top to bottom.

#43how in the holy hell do you read this? there are only 5 dates columns; how do you read days in month columns 6 and 7 (feb aug mar nov)? am i suppossed to matrix multiply this thing or what. im not normally too dumb for things but boy this is totally opaque to me.
The dates in a row correspond to the days beneath a month in the same row.
EG the 1st, 8th, 15th, 22nd, and 29th of January, April, and July all fall on Wednesday.
Or, May 18th is a Tuesday.

I think the idea is this:
1. On the left under "Dates" are the consecutive days of the month if you read column by column (of course not every month has 31 days).
2. The rows represent intervals of a week (hence each square is previous + 7).
3. Look first at the top left cell with June and Monday. That lines up with the days of the month 1, 8, 15, 22, 29. That's because those are all the Mondays of June.
4. Next row (same column) shows similar: The Tuesdays of June are 2, 9, 16, etc.
So you can start with any month (the columns) and look at the first row underneath to see which day of the week the month starts on and then follow the dates from there using the above logic.

#45For the last 3 years I've been printing several copies of the Compact Calendar by David Seah [1]. It's as its name implies a compact form calendar that spans the whole year in a single page, and leaves enough side space to annotate stuff as needed. It's very cool and useful, although it would be nice having an open-source based version (i.e. LibreOffice), for those of us that don't have an MS Office license... [1]: h…
What do you mean “open source”? XLS is the (previously proprietary) format used by older versions that’s (basically) just serialized structs. XLSX (which I see here) is the ZIP/XML based version based on an open standard[0][1]. LibreOffice opens those just fine from my experience; It’s the older binary format that LibreOffice can screw up with formatting.

I'm guessing you locate your month on the top, then locate the day of the month and it tells you what day of the week it is.
It's an interesting design exercise, but I can't imagine people using this day to day.

#48I'm not really sure what I am looking at. EDIT: Now I am. Clever!
I still am not. Could you explain?
To find the current day of the week, look at the row corresponding to the day of the month and the column corresponding to the month. There's a typo for the days 18-21 where there's two 18s.

#49Its not clear about such limitations as Feb <= 28/29 & Apr/Jun/Sep/Nov <= 30
You can tell that 2020 is a leap year because if you look up the day of the week for Feb. 28, it's Friday, and March 1st is a Sunday. That must mean that Feb. 29th is a Saturday. And indeed it is.

#50A few years back I took part in an online design challenge to make a pocket calendar - it was a lot of fun, my designs are here:

One of them is very similar to this one (Design 2) - I was tidying up someone else's idea. Dunno if David Seah's was related in any way or just people came up with the same idea.
