Divide Date & Time Columns

[kingmeesh242]

Good day,

How do I divide these two columns?

When I attempted to do so by creating a custom column in power query it said I could not use the divide (/) operator. The calculation I am trying to attempt is ((Visit End Time - Visit Start Time)/Visit Start Time) * 100 to create a visit time variance percentage. I got the calculation from this website https://codepal.ai/excel-formula-generator/query/sSEVcN4p/excel-formula-time-percentage-variance. Any suggestions or help with this would be greatly appreciated. Thanks!

Hi @tackytechtom,

You answered my question perfectly for the question I asked and the link I provided. I was actually looking for the equation of the (Actual Visit Time (Punch End Time - Punch Start Time) - Scheduled Visit Time (Visit End Time - Visit Start Time)) = Visit Duration Variance I was looking for / Scheduled Visit Time.

Hi @kingmeesh242 ,

How about this:

Here the M code:

Duration.TotalMinutes([Visit End Time] - [Visit Start Time]) / Duration.TotalMinutes(DateTime.Time([Visit Start Time]) - #time(0, 0, 0) )

Let me know if this helps 🙂
