How it's counted
Days since are counted from the date to today, not including the date itself.
In a spreadsheet
In Excel or Google Sheets, type =EDATE(TODAY(),-11) and format the cell as a date. EDATE keeps the same day of the month, or uses the last day when that month is shorter. To count from a different start date, use the date calculator.
