Although, the calendar month method may take into account the correct number days of the month, it is a common belief that the 30-day-month method or the '''8870''' hand method used for years before calculators is the method most often used. <ref> searchforancestors.com ''Tombstone Birthday Calculator'', http://www.searchforancestors.com/utility/birthday.html,  accessed 25 June 2021. Quote: "While you may think the calendar month method may be more reliable, be aware that many of the headstone and obituary ages at death appear to have been computed using the 30-day-month method. (The 30-day-month method assumes that all months have 30 days. It's an approximation which agrees with the calendar month method about 2/3 of the time.)"</ref> This 30 day month method would have been the easiest way for the individual to calculate the date for the tombstone inscription.
