Morphology

May + one

The form 'May 1' is directly compositional: combining the month name 'May' with the numeral '1' yields the date 'the first day of May,' which a B1 learner who knows months and numbers can readily interpret. Date expressions of this type are cross-linguistically common, so the specific holiday meaning (May Day) or festivities can be inferred or learned from context once the date is understood.

Etymology

May 1 comes from old spring celebrations when people danced around a maypole and put flowers on doors to welcome the season. In the 1800s workers used the same day for big protests for shorter working hours, so today May 1 can mean either a 'spring festival' or a 'workers' holiday'.
