Hey everyone,

I'm working on a formula in Power Fx that subtracts the end date from today's date. I'm encountering some data type errors because the NOW() function includes both date and time, causing issues with calculations. Ideally, I'd like to use a function that only considers the date portion.

In my current formula, even though the end date and the result of NOW() show the same date (e.g., 17/6 or 17 Jun), the difference (DATEDIFF) is -1 instead of the expected 0.

Any suggestions on how to tackle this? I'm looking for ways to calculate date only
Thanks in advance for your help!

@viet561995 ,

That is also a very good thing to post initially - I will have to step away here as I do not use them.

Thanks for your reply,

In my case, I'm actually working within the model-driven app, not canvas app. in this model driven app, the Power Fx is in preview mode. Im thinking the TODAY() function might not be available in the preview mode yet so i am trying to find another solution.

Additionally, I can confirm that the End Date field in my model-driven app is set up as a date only type field, so it's not storing any time information.

Hi @viet561995 ,

Today() certainly is supported

I am assuming 'End Date' in your formula is actually a valid date field or value.

Thanks for the suggestion! Unfortunately, I already tried using TODAY() in Power Fx, but it seems that function isn't supported. That's why I was using NOW() instead.
