Can `cal` show other Gregorian adoptions?

On my host I can show the [adoption of the Gregorian calendar](https://en.wikipedia.org/wiki/Adoption_of_the_Gregorian_calendar) as it occurred for [Great Britain and its colonies](https://en.wikipedia.org/wiki/Adoption_of_the_Gregorian_calendar#Great_Britain_and_its_colonies) in 1752: $ cal september 1752 September 1752 Su Mo Tu We Th Fr Sa 1 2 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 The corresponding adoption for [Denmark and Norway](https://en.wikipedia.org/wiki/Adoption_of_the_Gregorian_calendar#Denmark_and_Norway) happened much earlier: > Sunday, 18 February 1700, was followed by Monday, 1 March 1700. I thought I could override the timezone environment variable to show this, but that doesn't work: $ TZ=DK february 1700 February 1700 Su Mo Tu We Th Fr Sa 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 How do I get cal to show Denmark's adoption of the Gregorian calendar? My cal is supplied by [bsdmainutils](https://salsa.debian.org/meskes/bsdmainutils) version 11.1.2.
