Last Month
noun
The previous month is last month.
せんげつ
This is a jukugo word, which usually means on'yomi readings from the kanji. Since 月 has two on'yomi readings, here's a mnemonic to help you remember which one to use: As of last month, your centaur gets (せんげつ) up every night and comes to sleep in your bed. Apparently, he gets really bad nightmares. Poor little centaur.

先月の分は一万円です。

先月、ニューヨークでおあいしましたよね？
