You should know this ahead to fully enjoy that beauty of compact, mathematically sound week chart, and perhaps the accompanying momentary illusion that world makes sense again.
The next opportunity to enjoy most compact possible calendar page will be in 2038, so don’t miss it!
(Bonus: if you notice that 1st week is week 5 so apparently January 2027 also has 4 weeks–what gives? That’s because in ISO week numbering, first three days of January 2027 count as week 53 of 2026. In other words, week 1 of 2027 starts on January 4th.)
If your calendar starts with Sunday, this past February of 2026 was actually compact, and the next one is in 2037.
Does anyone actually use calendars that put Monday on the left? Not where I live but I haven’t seen the calendars of most of the world.
Hell yeah! And I’m confused af when Sunday happens to be on the left.
I live in Czechia (born in Slovakia) and you won’t see Sunday-first calendars around here unless they are imported. (I bet lot of people even don’t know that in some calendars in the world Monday is not the first!)
Roughly 160 countries (about 3.3 billion people) start the week on Monday. Virtually all European countries follow ISO 8601 and have adopted Monday as their start of the week

You’ll find both Sunday-first and Monday-first calendars here in Britain, though I couldn’t tell you the ratio and popularity of each.
I’m usually given one as a Christmas gift and that particular make are usually Monday-first, but last year’s was Sunday-first for the first time in ages, which took me by surprise.
Also, my computer preference is Monday first wherever it can be set.
That might derive from locale settings, but I’ve carried over configs for literally decades at this point, so I couldn’t tell you for sure.
I never knew this! I’ve never in my life seen a Monday first calendar in the US
Virtually all calendars do so in France.
