How to use it

What it does – The Hours of Sleep Calculator takes your age and instantly shows the amount of sleep you should aim for each night. The recommendation follows a simple rule: start with 8 hours and add 15 minutes for every year you’ve lived (age rounded down). Why it matters – Getting the right amount of sleep supports memory, metabolism, and overall health; too little or too much can affect performance and mood. How to read it – The result appears as total hours and minutes; use that as a nightly target and adjust for lifestyle factors. No complex charts or medical jargon—just a clear, age‑based guideline you can apply today. If you’re 30 years old, the calculator will show 15 hours 30 minutes, reflecting the 8‑hour base plus 30 × 15 minutes. Use this number as a benchmark, then fine‑tune based on how you feel after a week of consistent sleep.
Pro tips
- Round down the age if you’re between birthdays; the calculator uses whole years.
- If the result includes minutes over 60, convert to additional hours for easier tracking.
- Plan your bedtime to hit the target, allowing a 15‑minute buffer for interruptions.
- Don’t treat the number as a strict rule; adjust if you consistently feel rested earlier or later.
Real-life examples
