Monthly payments are the norm here, not fortnightly, so it seems natural to me that pay frequency match the frequency of bills, which are also monthly. I also set up my bills so that they are all due early in the month (around the 5th, so I have time to fix things if anything messes up my pay deposit). Then, the amount in my account is what I have to spend until the end of the month. To me, that is easier than having to consider how much will be deposited in the middle of the month and what bills still have to come in.
