Changed Payment Due Date

So my original due date was on the 26th of the month which was a pain to deal with.
I pay everything on the 29th of every month for items due on the first and then anything
beyond I pay on the 10th. Works out well.

So I went online and changed my due date back to the 15th instead of the 26th and now
it says I don't have a payment in July, which works for me, but I wondered if that was like
totally cool.

Anyone else done this with similar result?

 

I have done it for other bills, so they're kind of grouped together. 99.999% of institutions will allow you to change it to a date that you specify.
