How the tally and the next date are produced
Pick a season and the items that commonly come up for it appear as a check list. Ticking what you looked at gives the number checked, the total on the list, and the items still outstanding. Your own interval is then added to the last check date to produce the next one, and that is compared with the reference date to show the days remaining or the days overdue.
No official seasonal inspection list and no recommended interval are published here, because homes and their equipment differ too much for one table, and widely repeated figures are habit rather than standard. Written as of October 2026.
This tool counts items and dates only. It does not judge what you find, suggest repairs, or give response steps for an incident. Follow guidance from the US Federal Emergency Management Agency and the National Fire Protection Association, and leave equipment servicing to the manufacturer or a qualified trade.
Frequently Asked Questions
No official household seasonal list is published here. The built-in items are ones that come up commonly, and what actually matters depends on how your home and its equipment are built.
No recommended interval is published here. Enter the interval you have decided on, in months or days, and it is added to the last check date to give the next one.
If the target month has no 31st the date moves to the last day, so it becomes February 28, or February 29 in a leap year. Day intervals are counted straight through regardless of month length.
