The result assumes the days are spread evenly through each week. Real weeks vary.
The formula behind the planner
The planner uses one equation: calendar days equal the goal multiplied by seven, divided by the days you do per week, rounded up. The finish date is the start date plus those calendar days, minus one so that the start day counts as day one. Weeks needed is the calendar days divided by seven, rounded up.
It makes no allowance for holidays, illness or a changing schedule. That is deliberate: those are the parts that nobody but you can predict. Use the result as the earliest reasonable finish date and add a buffer.
Should I aim for a daily chain or a weekly target?
A daily chain suits a habit that is tiny and easy to repeat, such as a one-minute stretch. A weekly target suits habits that need rest or planning, such as strength training. Choosing the weekly rate honestly, rather than seven days by default, makes the plan more likely to survive.
If you are unsure, plan for fewer days than you hope to manage. Finishing early is far better for motivation than finishing late.
Worked examples
| Goal | Days per week | Calendar days | Weeks |
|---|---|---|---|
| 30 days | 7 | 30 | 5 |
| 50 sessions | 3 | 117 | 17 |
| 100 days | 5 | 140 | 20 |
| 200 days | 6 | 234 | 34 |
Building in a buffer
Add ten to twenty percent to the calendar days for the unexpected. If the planner says 140 days, plan for about 160. A finish date that is a little too generous keeps the plan positive, while a finish date that is too tight turns each missed day into a threat.

- Does the planner count rest days?
- Yes, through the days per week setting. Choose five if you take two rest days a week, and the planner will spread the goal over the calendar accordingly.
- What if I start missing days?
- Re-enter the days still to complete and today's date to get a new finish date. Planning again is more useful than treating the original date as fixed.
- Is a longer streak always better?
- Not necessarily. A streak is a tool for consistency, and a long streak that makes you anxious or pushes you to train through illness is not serving you. Choose goals you can sustain.
