FAQ
When does a 1-month warranty bought on January 31 end?
February has no 31st, so the last day of February (the 28th, or the 29th in leap years) is used. This is the same rule as the EDATE function in spreadsheets.
Should I choose the anniversary or the day before?
It depends on the wording of your warranty. “One year from the date of purchase” is interpreted differently by different makers, so if in doubt use the earlier date and check with the manufacturer.
