The bills are once a month but the specific due date for each can varry. For us some of our bills are due at the beginning of the month and some are due towards the end, but most are at the beginning.

Not really. Because my monthly bills don’t come at the same time each month. It would probably be harder to coordinate bills if you’re paid monthly here anyway. Makes more sense to have a steady cash flow imo. Imagine living paycheck to paycheck and your bill is due on the 28th, but you don’t get paid until the 1st. Some people might run out of money before their bill is due and they don’t get their next paycheck yet.
