What do 15 minutes a day add up to in a year?

Try the weekly and annual equivalent of a small daily change.

Published: 1 October 2026 · Examples use the stated assumptions.

Choose a calendar assumption

A daily habit and a weekday-only habit do not add up to the same annual duration. This workshop uses a 52-week model. Holidays, illness and weeks off are not automatically deducted. The result is a planning scenario, not a record of actual use.

15 minutes, 5 days a week

Weekly time is 15 × 5 = 75 minutes. The annual model gives 75 × 52 ÷ 60 = 65 hours. Dividing this into eight-hour blocks gives 8.125 blocks. These are not days of leave recovered from the calendar; they are another way to express the total duration.

What do you want to reduce or keep?

Not every minute spent on a screen has the same value. Talking to someone close to you, finding your way and scrolling without a purpose lose their meaning when lumped together. Choose one behaviour to change first. The aim is not zero screen time, but a measurable experiment that serves your priorities.

A small one-week experiment

Observe for three days, then try a daily 15-minute change for a week. Note what you did with the time you set aside. Missing a day should not turn the annual model into a measure of failure. Recalculate using the days you actually completed.
