The month after this one; the coming month. Used to refer to future events or plans in the month that follows the current one.

来月 refers to the month following the current one and can function as both a noun and time adverb.
TIME REFERENCE SERIES:
The 来 prefix means 'coming' or 'next' and appears in 来週 (next week) and 来年 (next year).
USAGE:
Like other time nouns, 来月 often appears without a particle: 来月引っ越します (I'm moving next month). Use の to connect to nouns: 来月の予定 (next month's plans).
