Re: Today IS payday...
"I ended up making sure all the bills were timed for the first fortnight of the month for that very reason."
As a variation I used to get bank statements in the middle of the month so I could work out how bad the remainder was going to be and prioritise things accordingly.
(Current bank adopted the practice of sending statements whenever there was a full page to print. It's now abandoned that practice and apparently sends out a statement after some random fraction of a full page has been generated. What they never seem to have worked out is what every other bank I've used over several decades has accomplished: print monthly and shove as many pages as that requires into a single envelope. The wonders of modern banking IT.)
