Hi Eco,

Try this in C2 and drag down as far as is needed.
=COUNTIF($B$2:B2,B2)

Hi, I need a formula to count the number of times an Item is repeated in
consecutive days from a list.

For example:
A B C
*******************
1 * Date Item Repeated
2 * 1-jun Item1 1
3 * 1-jun Item2 1
4 * 2-jun Item1 2
5 * 2-jun Item3 1
6 * 3-jun Item1 3
7 * 3-jun Item3 2
8 * 3-jun Item4 1
....
..
.

NOTES:
- My list contains consecutive days including weekends.
- Each Item is not repeated in the same day.
- Each day, the number of Items appeared could be different.
- My list is ordered by date from the older to the newest.

Thanks in advance for your help.
