What each result means

  • Years together = floor([Months]÷12)
  • and months = [Months] – 12×floor([Months]÷12)
  • and days = [Date] – addmonths([Wedding or start date], [Months])
  • Days together = [Date] – [Wedding or start date]
  • Next anniversary (number) = [Years together] + 1
  • Next anniversary date = addmonths([Wedding or start date], ([Years together] + 1)×12)
  • Days until the next anniversary = [Next anniversary date] – [Date]
  • Traditional gift for the next anniversary = [Next anniversary (number)]

Formula

Time together = date − wedding date (years, months, days) Next anniversary = wedding date + (completed years + 1) years
