How to Calculate 12 Months Before Today Manually
To calculate 12 months before today manually, subtract 12 from the current month number, borrowing from the previous year if it goes below month 1. If today's day of the month doesn't exist in the target month going backward (for example, the 31st landing in a month that only has 30 or 28 days), most calculators automatically roll over to the next valid day. Because months have different lengths, the exact calendar day count for this specific 12-month span is 365 days.
