Capitals
Braille letters are lower case unless marked. Days and months take the capital sign, dot 6, before their first letter (⠠⠙⠑⠉⠑⠍⠃⠑⠗). In all capitals, DECEMBER, two capital signs mark the whole word: ⠠⠠⠙⠑⠉⠑⠍⠃⠑⠗. More on capital letters in braille.
Grade 1 and Grade 2
This is uncontracted (Grade 1) braille, every letter written out, which is where learners start. Books, signs and labels mostly use Grade 2, where common letter groups and words take a single cell, so some words come out shorter there. See the Grade 2 contractions.
Remember it, don't just look it up
Days and months are spelled letter by letter, so the alphabet is what to learn. Braille a Day brings it back tomorrow to answer from memory, then again just before you'd forget. Five minutes a day.
