Questions people ask
The things that come up about birth day finders, answered plainly.
How is the weekday worked out for old dates?
By counting days in the proleptic Gregorian calendar — the modern calendar extended backwards. For dates before a country adopted it (1752 in Britain and its colonies, 1582 in Catholic Europe) the historical weekday differed, because eleven days were skipped in the changeover.
What is the rhyme?
Monday's child is fair of face, Tuesday's child is full of grace, and so on. It first appears in print in 1838, and is the reason this question gets asked at all.
