Autumn Planner

–days until the date
WhenDateTask
The target date defaults to the 2027 autumn equinox (September 23) - the astronomical start, per the US Naval Observatory seasons API. Point it at your own autumn deadline instead (first frost, family visit, the holiday run) and every row re-dates.
The detail tools: the autumn dates table for a decade of equinoxes, the first frost planner for the garden deadline, the autumn countdown for the plain number, and the daylight saving table for the clocks-back night.

Autumn is the season you prepare in, not the one you enjoy later: the furnace service that beats the first-cold-snap queue, the gutters that must be clean before the leaves finish falling, the tire swap before the first icy morning. This planner takes your autumn date - the 2027 equinox, September 23, by default - and dates the whole winterization run backward.

Bottom line: the two rows people skip are the two that cost the most - the heating service (emergency rates plus a weeks-long queue once the cold hits) and the gutter cleaning (clogged gutters do not announce themselves until the water is inside a wall). Both live at T-minus-30 and T-minus-21 for a reason.

The honest part: the default rows fit a temperate-climate house with a yard. Condo dwellers skip half the ladder; deep-winter regions move everything earlier by their first-frost date. The tool dates the steps; your climate sets the margins, and the first-frost planner carries the garden side.

How to use

  1. Set your autumn date - the equinox pre-fills, but your own deadline (first frost forecast, the holiday-travel run) works if that is the real clock.
  2. Read the table backward: heating at T-30, gutters at T-21, tires and drafts in the two weeks after, the rake rotation weekly from T-7.
  3. Bookmark the page: your date saves on this device, and the plan re-dates itself whenever the target moves.
Good to know — The 2027 autumn equinox lands Thursday, September 23 (US Naval Observatory tables) - the planner's default target. The row ladder: heating at T-30, gutters at T-21, tires at T-14, drafts at T-10, raking weekly from T-7, detectors at T-3. The seasonal logic underneath: first frost typically follows the equinox by 2-6 weeks depending on latitude, and every row before it is cheaper than the same row after it - the whole plan is an arbitrage on the first cold night.
Quick reference — Book the heating service before you want it - the T-minus-30 row is really a booking row, and the date you write down is the appointment, not the task. Everything else in the plan can slide a week with the weather; the technician slot cannot, because half the town is trying to book the same quiet week.

Frequently asked questions

When should I service my furnace or heating?

Thirty days before you expect to need it - the T-minus-30 row. HVAC techs run first-come-first-served until the first cold snap, then it is emergency rates and a two-week queue. A fall service also catches the carbon-monoxide risks (cracked heat exchangers, blocked vents) before the windows close for the season, which is why the detector test sits in the same plan at T-minus-3.

When should gutters be cleaned in fall?

Twice if you have trees: once as the bulk of the drop finishes (the T-minus-21 row) and once after the last leaves are down. The timing rule is 'before the first freeze' - water trapped in clogged gutters becomes ice dams, and ice dams become roof leaks. Thin, weekly rake-and-mulch rotations beat one giant pile for the lawn the same way.

When should I switch to winter tires?

Not a date - a temperature: the 7°C (45°F) rule says winter rubber goes on when average daily highs sit below it for a week, because all-season compounds harden and lose grip in the cold. For most northern states and Canada that lands mid-October to early November; the planner's T-minus-14 row from the equinox is the early-side reminder that booking the swap appointment needs.

What should I seal before winter?

The cheap leaks first: door sweeps, window caulk, the attic hatch - the draft audit is a candle-and-hand test that costs an afternoon. Sealing is the T-minus-10 row because it is the highest-return hour in the whole plan: draft sealing routinely trims double-digit percentages off heating bills, and every other winterization row only manages single digits.

How is this different from a fall cleanup checklist?

A checklist tells you what; this dates it, backward from the day winter starts mattering. The sequencing is the value: heating before the queue, gutters before the freeze, detectors before the windows close. Set the date once and every task gets a weekday - tasks with dates happen; tasks on lists do not.
