How cumulative pan use is counted
A pan leaves the impression of having been around for years without ever producing a number. This tool takes the date each pan went into use and how often it is used in a week, counts the cumulative uses and the days in use for each one, and shows the most-used pan, the one longest in use, and the total across them.
How the math runs
Cumulative uses divides the days from the first use to the reference date by 7 to get weeks, multiplies by the uses per week, and rounds down, because only completed uses are counted. Dates are built from year, month and day components separately, so month ends and leap years hold. A first used date later than the reference date is blocked with a message. Figures are current as of October 2026.
Limits and disclaimer
No coating lifespan, replacement point, or maximum usable temperature is offered here. Figures in this area are widely quoted but are not a published standard and have not been confirmed in authoritative sources. Follow the manufacturer's guidance on lifespan and replacement. The cumulative figure is a straight extension of the frequency you entered rather than a log of real use, so it is not a prediction, and the tool neither assesses the coating nor produces a score.
Frequently asked questions
No replacement point or coating lifespan is offered here. Both shift with the coating and how it is used, and neither has been confirmed in authoritative sources. Follow the manufacturer's guidance on lifespan and replacement.
No. No authoritative standard for the maximum temperature of a non-stick coating has been confirmed. This tool counts uses only.
No. The days from the first use to the reference date are divided by 7 to get weeks, multiplied by the uses per week, then rounded down. It is a straight extension of the frequency you entered.
