Small numbers, 12 weeks later

The same arithmetic for the most common amounts. One pattern is worth remembering: if you only count weekdays, the minutes a day are the hours you will have in 12 weeks.

The minutes are already in your day

Most days don’t lack thirty minutes. They lose them in pieces: a check of the feed between tasks, a video before starting, a scroll at the end of the evening. Your phone keeps the count.

  1. iPhone: Settings → Screen Time shows your daily average.
  2. Android: Settings → Digital Wellbeing shows today’s screen time.
  3. Pick a number you could take back on a normal day, not your best day.

Then give those apps a limit: on iPhone or on Android.

Minutes without a goal go back to the feed

Forty-two hours only add up to something if each session starts with a decision already made. Choose one goal, cut it into this week’s actions, and let the minutes go there.

Break a big goal into weeks and actions, or type it into the free 12-week planner.

The arithmetic, answered

How many hours is 30 minutes a day for 12 weeks?

42 hours: 30 minutes × 84 days = 2,520 minutes. On weekdays only, it is 30 hours.

What should the minutes go to?

One goal, broken into this week’s actions, so each session starts without deciding what to do. Here is how to break a goal into weeks.

How many hours is one hour a day for 12 weeks?

84 hours, or 60 hours if you only count weekdays.

Is 12 weeks 84 days?

Yes. 12 weeks × 7 days = 84 days, which is why the calculator multiplies by 84 when you count every day.

What if I skip days?

Count the days you will really use. Set the calculator to 5 or 6 days a week; a plan that survives a busy week beats one that needs every day.

How many hours is 30 minutes a day for a year?

182.5 hours: 30 minutes × 365 days = 10,950 minutes.

Give the minutes a job

12Focus gives the apps you choose a daily allowance and adds minutes each time you finish an action you planned, so the time you take back goes to the goal.
