What does monthlong mean?
Monthlong means lasting for a month or continuing throughout a month. The word is useful when describing a stay, journey, exhibition, course, investigation, or other event whose duration is a significant part of a calendar month. It is more specific than a general term such as “extended” and more readily conveys the scale of the period than saying merely “a month.” Although “monthlong” is not limited to events lasting exactly thirty days, it commonly refers to periods spanning most or all of a particular month. The closed form is standard in contemporary English, while “month-long” with a hyphen remains acceptable and often appears in editorial contexts for greater clarity.

Where does monthlong come from?
The word is a modern compound formed from “month” and the adjective “long.” “Month” comes through Old English from the Latin word mensis, meaning a lunar month or the period between new moons. “Long” has a separate Germanic origin and developed from an Old English adjective meaning extended in space or time.
How monthlong is actually used
The compound is normally written closed as “monthlong,” though the hyphenated form “month-long” is also standard and may be more readily understood. It is more precise than simply saying “long” when the duration is exactly or approximately one month.
