Use this result well

Inputs that matter
Self-reported daily hours for work/school, social media, streaming, gaming, and other use, plus age band and late-night context
Output to expect
Daily, weekly, monthly, and yearly totals; non-work equivalents; break priority; and age-aware habit prompts
How it works
Local aggregation capped at 16 hours per day, with transparent time multipliers and separate work versus recreational totals
  • Treat the result as a planning prompt based on self-report, not a diagnosis of sleep, eye, or mental-health effects.
  • Use the linked WHO/AAP material for age-specific context and seek individual clinical advice when symptoms or development are a concern.

Choose your path

Built around the job you need to finish

Turn a realistic daily screen-time breakdown into weekly/yearly context and safer habit prompts without presenting aggregate time as a medical diagnosis.

Adult habit reviewer

Separate work from leisure and see the annual scale of current habits.

Adjust five categories, review daily/weekly/yearly totals, and compare non-work alternatives.

Identifies one feasible leisure-time change without treating illustrative equivalents as predictions.

Parent or caregiver

Review age-aware guidance without applying a false universal two-hour rule.

Select the relevant age band, separate educational/work use, and read source-qualified family guidance.

Uses the result as a conversation/planning aid and consults pediatric guidance for individual needs.

Nighttime screen user

Notice possible sleep and activity displacement patterns.

Enable late-night use, inspect break/sleep/activity prompts, and apply the 20-20-20 reminder.

Understands the prompts are behavioral signals based on self-report, not clinical risk scores.

Reference & details

How it works

Time Aggregation

Five non-negative category values are summed with a 16-hour daily cap. Weekly, 30-day monthly, and 365-day yearly figures assume the entered day repeats unchanged.

Weekly hours = Daily total × 7; Yearly hours = Daily total × 365

Work and Leisure Separation

Alternative-activity estimates and age guidance use social, entertainment, gaming, and other time, not work/school time. The displayed activity counts divide annual leisure hours by simplified time assumptions and are not forecasts.

Behavioral Guidance Boundaries

Aggregate hours cannot diagnose eye strain or reveal continuous sessions. Age guidance distinguishes the approximately one-hour recommendation for ages 2–5 from AAP family-plan guidance for older children and teens. Persistent symptoms or child-development concerns require qualified care.

Example Scenarios

An adult separates required work time from social, streaming, and gaming use, then chooses one realistic evening reduction instead of treating all screen hours as equally avoidable.

A caregiver selects an age band, reviews recreational rather than school use, and uses the guidance to discuss sleep, activity, and family routines rather than impose a false universal two-hour cap.

A user flags late-night social or streaming use and treats the resulting sleep and break messages as prompts to test a routine change, not as a medical assessment.

FAQ

Time multiplication is deterministic, but the input is a self-report and the 16-hour waking-day model is an assumption. Device tracking can improve the estimate; overlapping screens and background playback should not be double-counted.

Yes, our Screen Time Calculator is completely free with no registration required. There are no usage limits, hidden fees, or account setup — just open the tool and calculate.

Yes, the Screen Time Calculator is fully responsive and works on all devices including phones, tablets, and desktops. All calculations run in your browser for fast, private results.

It totals five daily categories, separates non-work use, scales the same daily pattern to week/month/year, and shows illustrative time equivalents. It does not measure session length, eye strain, sleep quality, addiction, or clinical risk.

The category calculations run in the browser and the tool does not require account credentials or device-history uploads. Use rounded self-reports rather than entering sensitive workplace or child information.

About Screen Time Calculator

Break a self-reported day into work/school, social, streaming, gaming, and other screen use. Keep the total within a 16-hour waking-day model, separate leisure from required use, and treat health prompts and activity equivalents as conversation aids rather than diagnoses or forecasts.
