Playing with date-fns

I used to work with moment, and then moved on to date-fns. Whenever I want to format a date other than yyyy-MM-dd, I have to go see the docs. So I'm adding my most used formatting strings here.

Year
yyyy    2021
yy      21
Month
M       1, 2, ..., 12
Mo      1st, 2nd, ..., 12th	
MM      01, 02, ..., 12
MMM     Jan, Feb, ..., Dec
MMMM    January, February, ..., December
Day of month
d       1, 2, ..., 31
do      1st, 2nd, ..., 31st
dd      01, 02, ..., 31
Hour (1 - 12)
h       1, 2, ..., 11, 12	
ho      1st, 2nd, ..., 11th, 12th
hh      01, 02, ..., 11, 12
Hour (0 - 23)
H       0, 1, 2, ..., 23	
Ho      0th, 1st, 2nd, ..., 23rd
HH      00, 01, 02, ..., 23
