"first of the month" or "new month, new money"

the first of the month
  is a new beginning
I set my budget
I transfer monies where they need to be
I take count
and I give an accounting

Get it on Friday, spend it on Friday
  was the motto

now I get it on the first and try
  to keep track of spending
so it's not all gone by the fifteenth
  at least.
