EVEs

An eve is the period immediately preceding an event, often the day or evening before. In general usage, "on the eve of" signals that something is imminent; as a noun, "the eve" can refer to that pre-event time. The phrase is commonly used with holidays: Christmas Eve, New Year’s Eve, All Hallows’ Eve (Halloween).

Etymology: The word derives from Old English æfen, meaning evening; the sense "the evening before" developed in Middle English. The basic sense of evening persists in the modern usage of "eve" to denote the pre-event time.

Plural usage: The plural "eves" is used when speaking of multiple instances of such pre-event periods, e.g., "the eves of several holidays." It is also occasionally used in literary or historical contexts as a poetic plural.

As a proper noun, Eve is a female given name; if capitalized, "Eve" refers to a person, and "Eves" would be the plural form when referencing multiple people named Eve or, less commonly, a surname.
