how 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.

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.

My thought was "Your calendar is bad and you should feel bad." It's a reference and I don't actually mean that, except as a reaction to seeing it after clicking the title on HN which had me expecting something I might want to use.

I am guessing that people outside the US do not have as much trouble, as the format is naturally dd/mm/yyyy instead of mm/dd/yy, so reading left to right is more natural.

It took me a brief moment to acclimate to this, but after I did I felt it was pretty straightforward and elegant.

To me, this looks complicated as well. For a full year calendar I prefer a standard one https://calendaroptions.com/2020-calendar/. If you're into space, NASA has a pretty cool science calendar(PDF) https://eospso.nasa.gov/sites/default/files/publications/202...

Brit here. While this is undoubtedly clever, it confuses the hell out of me!

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.

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.
