How to round minutes in time to the nearest hour

[TessGaston]

Hello everybody,

I have a field in format of time like 9:03:45 or 9:46:12.

I need to make a new field where I would round the times to the nearest hour, for example:

9:03:45 -> 9:00

9:46:12 -> 10:00

How can I do that in Power BI?

Thank you.

Hi @TessGaston

You can do this in DAX or M languages depending where you want the calculation to happen.

If <original time> is the original time value:

DAX:

Round time to nearest hour ( TIME(1,0,0) = 1/24 representing an hour) and add a zero time value to ensure the expression is cast as a Time.

MROUND ( <original time>, TIME ( 1, 0, 0 ) ) + TIME ( 0, 0, 0 )

M:

There isn't an equivalent of MROUND in M, so instead multiply the time by 24 to express it as a number of hours, then round, then divide by 24 and convert to a Time type.

Time.From( Number.Round( Number.From( <original time> ) * 24 ) / 24 )

Owen
