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.
It's an interesting design exercise, but I can't imagine people using this day to day.
It took me a brief moment to acclimate to this, but after I did I felt it was pretty straightforward and elegant.
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.
EG the 1st, 8th, 15th, 22nd, and 29th of January, April, and July all fall on Wednesday.
Or, May 18th is a Tuesday.
