Average Function

[SMT2]

I have to compute the average of one number per day for a 30 day period. However, I need to drop the previous day and add the next day to the formula so it's always a 30 day period. Any help would be appreciated.

Administrative Note:

Welcome to the forum.

An AVERAGEIFS with today's date and today minus 30 as the citeria would do it.

Is your forum profile showing the version of Excel that you need this to work for?

Members will tailor the solutions they offer to the version of Office (Excel, NOT Windows) that you have. Please check that your forum profile is up-to-date in this respect. If you aren't sure, in Excel go to File | Account and report what it says below the MS logo at the top of that page. If your version is for Mac, please also state this.

The three most recent versions of Excel are Excel 2019, Excel 2021 and MS365 - if you are using MS365, please give this name along with the release number in your profile (e.g. MS365 Version 2211). This is in the About Excel section further down the Account page.

Thanks.
