Where's the 21st?

[mynegation]

Probably copy paste error. There are two of 18.

[teekert]

How does one change the year then?

[asdf21]

First, you create the universe.

Then you build a new year of the calendar.

[0xdeadbeefbabe]

Then you argue.

[spongeb00b]

Reuse one of the 18ths

I'd rather keep one of mine as a spare. I frequently find myself needing more time around the middle of the month.
