Primarily used as a suffix attached to a year number (e.g., 2024年暮れ) to mean 'the end of that year'. Rarely used as a standalone noun; the more common standalone term is 年末 (ねんまつ).
I plan to move at the end of 2024.
I haven't sent out my year-end greetings yet.
Compound of 年 (ねん, 'year') and 暮れ (くれ, 'end'). The reading ねんくれ is a straightforward combination of the on'yomi of 年 and the kun'yomi of 暮れ.
