Unexpected behavior with "+(months):1"

[TechieInAK]

I’m not sure if I’m missing something or not but I noticed something I find odd about the “+(months)” function. The reference states the following:

… +(months):
Adds/subtracts months to the date and returns the result. Use a negative number to subtract months.

Yet, when I tried to add one month from today’s date (August 31), I ended up with October 1:

Since September is only 30 days, compared to 31 in August, am I seeing 30 days being added and the resulting date being 10/1 as opposed to just the month being changed?

My original intent was to get to September 1 by adding a month and changing the date to 1. Because of the above, I did the reverse: I changed the current date to 1 and then added one month, which made it September 1. However, that doesn’t seem consistent with what happened above either…if it was 30 days added, as an average, I would have expected August 31, not September 1.

Am I missing something obvious?

Well you could use a conditional that goes something like this:

When Current Date/Time +(months): 1 extract month - Current Date/Time extract month is equal to or greater than 2, only add 27 days and then change the day to 1.

Something like that should work. Good luck,
Daniel

Thanks. I’ll play around with that a bit.

Great, let me know how you get on.
