bin nih un it tah tsoh
Your word for today should be familiar because it’s not that much different from Bini’anit’ą́ą́ts’ósí - the word for August.
Last month was the time of the lean harvest, so this month is the month of the bigger harvest. You can tell the difference by the last part of the word -tsoh.
So, today’s word is the Navajo term for the month of September.
