Date Difference between 2 dates from 2 rows
Hi All,
| Program | Milestone | Dates | Delay days |
| KL-41 | A0 | 06-Nov-25 | |
| KL-41 | P1 | 17-Nov-25 | |
| DH-05 | A0 | 22-Jan-25 | |
| DH-05 | P1 | 29-Aug-25 | |
| Ak-220 | A0 | 10-Aug-23 | |
| Ak-220 | P1 | 03-Nov-25 |
In Power BI, I want to calculate the number of days between the P1 and A0 dates for each program.
For example:
For KL-41, the delay should be 11 days, which is the difference between (17-Nov-2025) – (06-Nov-2025).
Could you please guide me on how to achieve this in DAX?
Thanks in advance!

Option 1: Calculated Column
If you want the delay at the program level, create a calculated column in your table:
Delay Days =
VAR ProgramID = Table1[Program]
VAR A0Date =
CALCULATE (
MIN ( Table1[Dates] ),
Table1[Program] = ProgramID,
Table1[Milestone] = "A0"
)
VAR P1Date =
CALCULATE (
MIN ( Table1[Dates] ),
Table1[Program] = ProgramID,
Table1[Milestone] = "P1"
)
RETURN
DATEDIFF ( A0Date, P1Date, DAY )
This will give you the days difference for each program.Option 2: Measure
If you only need it as a measure (e.g., in a table visual with Program):
Delay Days =
VAR A0Date =
CALCULATE (
MIN ( Table1[Dates] ),
Table1[Milestone] = "A0"
)
VAR P1Date =
CALCULATE (
MIN ( Table1[Dates] ),
Table1[Milestone] = "P1"
)
RETURN
DATEDIFF ( A0Date, P1Date, DAY )
When you put this measure in a table visual with Program, it will show the delay.Anilkumardoddi , Create a calculated column
DelayDays =
VAR A0Date = CALCULATE(
MAX('YourTable'[Dates]),
'YourTable'[Milestone] = "A0"
)
VAR P1Date = CALCULATE(
MAX('YourTable'[Dates]),
'YourTable'[Milestone] = "P1"
)
RETURN
DATEDIFF(A0Date, P1Date, DAY)
