Well, having too much liquidity is one of the reasons I know when payday is. If you have direct deposit, do you just let your check sit in your checking account (or where ever it is desposited)? I don't have funds automatically moved to various accounts, I do it by hand because sometimes things come up and funds need to be re-appropriated. That is probably why I know when payday is, I have banking to do!
I generally don't know exactly when payday is, but I know it's a bit before the last weekend of the month, and I know most bills have to be paid by on or after the last weekend of the month. So last Sunday of the month is banking day.
