Single-letter abbreviations for months
For, reasons, I want to be able to express dates as pairs of letters representing the day of the month and the month of the year. (Still working on how to letterize dates after 26.)
Half the months are easy: just give them their first letter. But for months that share initials, I've derived a "script" to give each one a unique associated letter. Like amino acids!
Here are the abbreviations and associated rationales.
January = J
February = F
March = R (has "R" pronounced in it; M is actually going to someone unusual)
April = L (has "L" pronounced at the end)
May = A
June = U (has a U, less awkward than Q)
July = Y (has a Y, partially pronounced)
August = M (the one place where I get clever) This one's a biology joke. In RNA translation, AUG is the "start making amino acids here" codon. It also codes for methionine. Methionine is abbreviated Met
or M.
The rest of these are what you'd expect:
September = S
October = O
November = N
December = D
