Calculating the difference between two date/times in Flow compose with dynamic values

Inside apply each (which contains Sp List items)  , i would like to calculate date difference. Scenario is 

expiray date (column of SP list item ) minus today's date is it equal to 90 days (this is again valye of list item field , will be dynamic value).

I tried many ways but doesn't seems to be working. I tried adddays but it takes integer as 2nd parameter , i tried to use dateDiff but doesn;t seems valid for MS flow.

 

Any help is aprreciated !

Hi @maheshkhisteLiv,

 

Could you please share a screenshot of your flow's configuration?

Do you want to filter SharePoint list items where expiry date minus today's date is equal to 90?

 

It is not simple to calculate the difference between two date/times in Microsoft Flow currently, if you want to filter SharePoint list items where expiry date minus today's date is equal to 90, you could consider take a try with following workaround as an alternative way:

 

I have created a SharePoint list on my side and the data structure of it as below:2.JPG

Note: The expiry date column is a Date type column in my SharePoint list.

 

I have made a test on my side and please take a try with the following workaround:

  • Add a "Recurrence" trigger, Interval set to 1 and Frequency set to Day.
  • Add a "Get items" action, specify Site Address and List Name.
  • Add a "Apply to each", input parameter set to output of "Get items" action.
  • Within "Apply to each" action, add a Condition, left input box set to following formula:

 

formatDateTime(addDays(utcNow(), 90), 'yyyy-MM-dd')

right input box set to expiry date dynamic content of "Get items" action, within middle drop down, choose is equal to.

 

 

 

Or you could consider take a try to click "Edit in advanced mode", then type the following formula:

 

@equals(formatDateTime(addDays(utcNow(), 90), 'yyyy-MM-dd'), items('Apply_to_each')?['expiry_x0020_date'])

Within "If/yes" branch of Condition, add a "Send me an email notification" action.

The flow works successfully as below:6.JPG

 

 

In addition, the dateDiff() function is not supported in Microsoft Flow currently, if you would like this feature to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:

I did read that information, but not seeing anything that's specifically related to dates.  So one thing that works is wrapping my field in 'year ( date )'...so it clearly understands that my field is a date.  Am I to assume at this point that the FLOW language doesn't know how to format the dates?  This is a huge impact to our process...so just making sure before I reach this conclusion.
