Incorrect Axes Label in Swizec's punchcard

[labcoder]

In the graphic of your punchcard, there are two '12a's. The second one should be 12p. Minor issue.

[Swizec]

I'm never sure which one should be which. I think midnight is 12p and noon is 12a.

Howver, they should not both be 12a. That's a bug ....

It's the opposite: 12p is noon; 12a is midnight. You could use 12n and 12m, instead.
