Zone cleaning belongs to Marla Cilley, better known as the FlyLady, who has coached people through it for years at FlyLady.net. Her clearest account of how the zones rotate is a reply to a puzzled reader, Please Explain the Zones, and the five zones, the week each one gets and the fifteen-minute limit are all her ideas. This calendar is an independent tool built around them. Marla Cilley and FlyLady and Company did not make it, have not reviewed it and do not endorse it.

What zone cleaning asks of you

Instead of cleaning the whole house on one exhausting day, you split it into five zones and give each zone one week of the month. Every day that week you spend fifteen minutes on a detail job in that zone only: the cabinet fronts, the grout, the floor under the bed. When the time is up, you stop, finished or not. By the end of the month every part of the home has had its week, and no day asked for more than a quarter of an hour.

FlyLady's zones run in this order:

1. the entrance, front porch and dining room
2. the kitchen
3. the main bathroom plus one other room, such as an office or a child's room
4. the main bedroom, with its closet and bathroom
5. the living room

She asks newcomers to keep her order, so that everyone is in the same rooms in the same week, and says you can draw your own zones once the habit has taken. She is also clear that clutter comes before detail work: if a zone is buried, its fifteen minutes go to clearing it.

How the weeks line up

Months don't divide neatly into five weeks, so a fixed chart can't tell you which zone a given Tuesday belongs to. FlyLady's weeks start on Sunday. This calendar counts zone one from the week that holds the month's first weekday, moves to the next zone every Sunday, and gives zone five whatever days are left. That means the last days of one month and the first days of the next often share a week, some months leave zone five a day or two, and a February that starts on a Sunday leaves it nothing at all. The calendar washes each week in its zone's color, so none of this needs working out.

How this page works

Today's card shows the zone that is up and one mission from its list. Missions come least recently done first, so a zone with more missions than mission days works through all of them over the months. Press start and the timer counts down the fifteen minutes. It keeps counting past zero if you keep going, and it logs the real time when you press done. If you worked without it, tap roughly how long the mission took.

Each logged mission lands on the calendar as its minutes. A mission day that passes without one gets a dash. Skips count only from your first logged mission, and only today can be marked, so yesterday stays as it was.

Each zone holds up to three rooms and seven missions, added with a tap or typed. Weekdays are mission days to begin with; switch any day on or off.

The two things it tells you

Which zone keeps getting skipped. Most homes have a room that loses the argument, often one that guests never see. The reading looks at each zone's last ten mission days and names a zone only when it clearly trails the rest. When the misses are spread across the house instead, it says that, because then the trouble is the days rather than a room.

How long the missions really take. People plan around the best case, a habit psychologists call the planning fallacy. In one well-known study of it, students expected to finish their theses in about thirty-four days and took closer to fifty-five. A mission you think of as fifteen minutes may be running twenty-five every time, and that is how the fifteen-minute promise quietly breaks. The calendar averages your real minutes and points to the zone whose missions run longest, so you can see which list needs smaller jobs.

What the evidence does and doesn't say

No trial has tested zone cleaning itself. What has good support is the habit underneath it: keeping a written record of progress. A meta-analysis of 138 studies found that prompting people to monitor their progress helped them reach their goals, and that the effect was larger when the progress was physically recorded. A calendar filling with minutes is exactly that kind of record. Whether a cleaner home leaves you calmer is personal and nobody can promise it. The method's real promise is smaller and steadier: no part of the house goes months without a turn.

When to use it

Start on any day. Set up your zones once, then open the calendar for fifteen minutes on each mission day, and let a missed day go rather than doubling up the next. If the house needs clearing before it can be detail-cleaned, run the Declutter Challenge first. The zones sit inside FlyLady's larger system of daily routines, and the Home Routines Journal is where yours can live. For the room that gets the most wear, the Kitchen Cleaning Checklist goes further into zone two.
