Every household runs on dates that come back: renewals, expirations, birthdays, the filter nobody remembers. Most cost money, or feelings, when they slip. Here's the full list, by category, with how often each one comes around. Checked October 2026.
People
Birthdays and anniversaries
Friends, parents, in-laws, nieces and nephews, and your own anniversary. See how to remember birthdays for a setup that works.
The holidays your family keeps
Mother's Day is Sunday, May 9, 2027 and Father's Day is Sunday, June 20, 2027. Add the ones your family celebrates, with enough lead time to plan.
Documents
Passports
Kids' passports expire first and can't be renewed by mail. Many countries want months of validity left when you arrive. Check every passport in the house.
Driver's licenses and IDs
Look at each card in the house and write the expiry down. Most people find out at a rental counter or the airport.
The car
Registration
In Texas you can renew up to 90 days early, and emissions testing comes first in DFW counties. See your renewal window.
Car insurance renewal
The month the premium tends to change. Worth a reminder a few weeks ahead so you can compare.
The home
HVAC air filter
ENERGY STAR's rule of thumb: check it every month and change it at least every three months.
Smoke alarms
Test them monthly, replace batteries at least once a year if they aren't sealed 10-year units, and replace the alarms themselves every 10 years.
Homestead exemption and appraisal protest
File the homestead exemption once (and answer any re-check letter); watch for the appraisal notice each spring. The Texas homeowner checklist has the full house calendar.
Money
Trials and subscriptions
The day a trial turns into a charge, and the annual renewals that bill once a year. Find the exact bill date.
Warranties and return windows
The return-by date on anything still in the box, and the warranty end date on anything that might break.
Make it one list
Put every date above in one place the whole house can see, with one nudge ahead of each. That's the whole idea behind Forgor: no to-do pile, nothing ever overdue, and each date rolls forward on its own. Not sure where you stand? Take the 60-second test.
