Is there a formula for upcoming date using formula in Google sheet based on condition?

问题

I have a google sheet where I need to get the next upcoming date based on the start date set in column A

Any pointers are greatly appreciated? I am unable exhibit the efforts as I am completely new to this sort of recurrence using Google sheets

This behavior (the next date from today including today) could be implemented manually by this formula:

={
  "Next date from today";
  ARRAYFORMULA(
    IFS(
      A2:A >= TODAY(),
        A2:A,
      B2:B = "Daily",
        TODAY() + MOD(TODAY() - A2:A, C2:C),
      B2:B = "Weekly",
        TODAY() + MOD(TODAY() - A2:A, 7 * C2:C),
      B2:B = "Monthly",
        EDATE(A2:A, ROUNDUP((12 * (YEAR(TODAY()) - YEAR(A2:A)) + (MONTH(TODAY()) - MONTH(A2:A)) - IF(DAY(TODAY()) < DAY(A2:A), 1, 0)) / C2:C, 0) * C2:C),
      True,
        ""
    )
  )
}

For additional options (like "every 2nd monday of the month" and others) additional options should be implemented in that IFS part.

If you are interested in a trivial case where the next date from the start date (column F:F on the screenshot) is needed, then the formula would be much simpler:

={
  "Next date";
  ARRAYFORMULA(
    IFS(
      B2:B = "Daily",
        A2:A + C2:C,
      B2:B = "Weekly",
        A2:A + 7 * C2:C,
      B2:B = "Monthly",
        EDATE(A2:A, C2:C),
      True,
        ""
    )
  )
}

Again, for additional options you'll need to add corresponding part to the IFS.

回答2:

You could use IFS to check Frequency, and:

If Daily, add Count value to start date.
If Weekly, add Count value multiplied by 7.
If Monthly, since not all months have the same duration, retrieve the YEAR, MONTH and DAY indexes, add Count to the MONTH index, and set a new DATE, EDIT: or as suggested by kishkin, use EDATE.

It could be something like this:

=ARRAYFORMULA(IFNA(IFS(
    B2:B = "Daily", A2:A + C2:C,
    B2:B = "Weekly", A2:A + 7 * C2:C,
    B2:B = "Monthly", EDATE(A2:A,C2:C)
)))
