How the date is worked out
Start with today as day 0, then count 120 calendar days forward, including weekends and any leap day. A hundred and twenty days is about four months, and it spans at least 17 weekends. Tick Count today as day 1 if your deadline includes today, which makes the answer one day earlier.
