Frequently asked questions

What does the Screen time calculator actually compute?

It takes Hours per day and derives Per week (hours), Per year (hours) and Per year (full days) from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

A single value: Hours per day. Nothing else is required — no account, no file upload.

Can you show a worked example?

With Hours per day = 4, the calculator returns Per week (hours) = 28, Per year (hours) = 1,460 and Per year (full days) = 60.833. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What happens if I enter larger values?

It moves a lot. Using Hours per day = 8 instead, Per week (hours) goes from 28 to 56 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Hours per day = 2, Per week (hours) comes out at 14. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Answering a scheduling question exactly: how many working days until a deadline, what date falls sixty days out, and what time that is for a colleague elsewhere.

What is the most common mistake?

Counting days by subtracting dates and forgetting whether the endpoints are included. Inclusive and exclusive counts differ by one, which is the difference between meeting a deadline and missing it.

What is the difference between the Screen time calculator and the Time duration calculator?

This one returns Per week (hours) and Per year (hours); the Time duration calculator returns Hours and Minutes. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Zombie survival time calculator is the closest one after this: When the outbreak hits, how long would you last? Choose your location, shelter, weapon, fitness, group and supplies, and this apocalyptic calculator estimates your survival time in days and weeks — and awards you a survivor rank, from zombie chow to wasteland legend.

What else is worth having open alongside it?

Daily Time Savings Calculator and Email Reply Time Calculator — they come up in the same task often enough to be worth a second tab.
