Can I perform math functions on a date data type?

[c-yun]

Hello,

I want to perform the following Excel function in Alteryx: =INT((B2-1)/7)*7+1.

How can I convert this formula into Alteryx syntax so I can use it in the formula tool?

Can I get a result using a different tool too?

I think you are trying to get the date of Sunday (as beginning of the week) for the dates list.

How can I add an IF statement to your formula that will give me the original start date if the original start date is already a Sunday?

When I enter the formula as it is currently, it gives me the previous Sunday date.

Hello @c-yun 

One way to tackle this would be to add a data time parse tool in, before the formula, to extract the day.

After this, you can edit the formula with an If statement, such that if the day = Sunday, then don't change the date, else, do change the date. 

 

Please let me know how you get on.
