Calculating the Start Month of a task relative to the start date of the project (Project Month Number) RRS feed

  • Question

  • Hi,

    I need to report a project in term of Months since the start of the project.

    to do so I created a custom field (Text 1), with thsi formula: (ProjDateDiff([Project Start];[Start];[Project Calendar])/[Minutes Per Day])

    As pero this blog:

    However, I need the relative month numer.

    My naive approach was dividing by 30 for an estimate. But the errors start to become significant halfway through the second year of the project ((ProjDateDiff([Project Start];[Start];[Project Calendar])/[Minutes Per Day])/30).

    Any ideas would be welcomed,

    Thank you,

  • Mata,

    I assume you want calendar months, not working months. Try the following formula

    Text1 = "Mon " & DateDiff("m",[Project Start],[Start]) + 1

    Hope this helps.
