Can you calculate, on which day is our anniversary? # Puzzle

Anniversary is on 23rd of the month

She will collect 276 books on 23rd day of the month.

1 + 2 + 3 + ……. 21 + 22 + 23 = 276

It reminds me of a formula we learnt in school

the sum of series 1 + 2 + 3……. n

is n x (n+1)/2

That was a good learning 🙂
