Can vs. May: Usage Guide
Can and may are most frequently interchangeable in uses indicating possibility; because the possibility of one's doing something may depend on another's compliance, they have also become interchangeable in the sense that means "to have permission." The use of can to ask or grant permission has been common since the 19th century and is well established, although some feel may is more appropriate in formal contexts. May is relatively rare in negative constructions (mayn't is not common); cannot and can't are usual in such contexts.

: the fifth month of the year
Etymology
Noun
from Middle English May (fifth month), from early French mai (same meaning), from Latin Maius, originally, "third month," from Maia "Roman goddess of spring"
Word Origin
Among the gods and goddesses worshipped by the ancient Romans was one known as Maia, a goddess of spring. In spring the Romans would make offerings to her on the first day of a month they called Maius, meaning "of Maia." The name of the Roman month was borrowed into early French as mai and later into English as May. For the early Romans Maius was the third month of the year; but after January and February were added, May became the fifth month.
