How to Calculate the number of rows that meet the condition as a new column

[equlibrum52]

I'm new one in PowerBi world and I need your help. I would like to add a new column to my fact table that will count the number of row for a date in a given record. So e.g. for the first record, return  the number of all rows from 2021/12/09. and so on for the second line, the number of all rows in 2021/12/08. Is it possible? Would be grateful for any help.

id	date	New Column
1	2021.12.09	2
2	2021.12.08	1
3	2021.12.09	2

You can also create a measure with below Dax

Count Rows = Count('Table'[Date])

Please confirm if this works for you..!

@equlibrum52 you can easily add a column using the following but always better to add a measure

Count Column = CALCULATE ( COUNTROWS ( YourTable ), ALLEXCEPT ( YourTable, YourTable[Date] ) )
