Roll a due date that lands on a weekend forward to the next business day with WEEKDAY
WEEKDAY turns any date into a plain number for the day of the week it falls on, and a number is something IF can test and arithmetic can act on — which is what turns "if it's a weekend, push it" into one formula instead of a separate rule for Saturday and another for Sunday.
Task:
You process accounts-receivable invoices for a regional utility company. Your bank's ACH system doesn't process payments on Saturdays or Sundays, so any invoice due on a weekend has to be pushed out to the following Monday before it's sent — a due date that already falls on a weekday is left exactly where it is. In column C, work out each invoice's adjusted due date: if the due date in column B is a Saturday, add two days; if it's a Sunday, add one day; otherwise leave it unchanged. Fill in rows 2 through 6.
