the same way we know that 'T' is for 'Tuesday' and 'Th' is for 'Thursday.'
As a non native speaker I have to admit I actually didn't know that.
But in German you also use two letters for all the weekdays.
Mo, Di, Mi, Do, Fr, Sa, So.
But it is a popular riddle for children to ask
M, D, M, D, what comes next?
I've seen systems in university use T for Tuesday and R for Thursday but they needed to print to paper with a single character wide column for day
Still, most people understand if I use MTWRF
Why R and not H?
For people who use comically thick Irish accents and say “Tursday,” I have to assume.

You might be onto something.
