Issues with time calculation (months)

[scottgm]

Hello all, 

I am building a workflow where I need to add/remove x-number of days to either the beginning or end of current, previous and next month. I have this part nailed down and working as expected. The date calculations are based on 3 initial values using these calculations:

CurrentMonth =  (expecting May)

startOfMonth(utcNow())

PreviousMonth =  Expecting April --> Actual is March

subtractFromTime(outputs('CurrentMonth'),1,'Month')

NextMonth = (expecting June)

startOfMonth(addToTime(utcNow(),1,'Month'))

This all worked as expected a few days ago, but now when I test on 1st May. The value for PreviousMonth is returning March 31st. My best guess is that by subtracting 1 Month, it is actually subtracting 31 days? 

I could work around this by subtracting 4-weeks rather than 1-month but I'd like to know if I am missing anything here or if someone has seen a similar issue?

Thanks,

Scott

Hi @scottgm ,

Thanks for feedback.

The issue could be reproduced by me. I will help report it.

Further, I found that you could get the previous month without returning to the start of the month, please try with the following code:

startofmonth(getPastTime(1,'month'))

startofmonth(subtractFromTime(utcNow(),1,'month'))

Please take a try with above function.

Best regards,

Mabel

Thank you @v-yamao-msft i'm glad it wasn't just me. 

I'll go with the workaround for now.

Cheers,
