How the date is worked out
Start with today as day 0, then count 30 calendar days forward, including weekends and any leap day. Thirty days is shorter than most calendar months, so it usually lands a day or so before the same date next month. Tick Count today as day 1 if your deadline includes today, which makes the answer one day earlier.
