Choose the stage you’re tracking today.

Bedtime

Use local time, like 20:45.

Wake time

If wake is next day, still enter time.

Sleep latency (minutes)

Time to fall asleep after bed.

Night wakings (count)

Include feedings or bathroom trips.

Avg waking duration (minutes)

Typical minutes awake each time.

Nap count (0–3)

Set naps you want to include.

Nap 1 (minutes)

Nap 2 (minutes)

Nap 3 (minutes)

Screen time before bed (minutes)

Total screen minutes in the last hour.

Caffeine after 2pm?

Applies to adults and teens.

Exercise level

Any activity earlier in the day counts.

Sleep quality (1–5)

Subjective rating helps trend tracking.

Notes (optional)

Keep notes short so you can compare days.

Example Data Table

Stage	Bedtime	Wake	Wakings	Naps	Total sleep (24h)	Efficiency	Score
Infant (4–11 months)	20:30	06:15	2	2 (60, 45)	13h 05m	86%	78
Pregnancy: trimester 3	22:45	06:30	3	0	06h 40m	82%	62
Toddler (1–2 years)	21:00	06:30	1	1 (75)	12h 45m	90%	86

Use the table to understand how inputs shape totals and scores.

Formula Used

Time in Bed (minutes) = difference between wake time and bedtime (handles crossing midnight).
Awake from Wakings = night wakings × average waking duration.
Estimated Sleep = time in bed − sleep latency − awake from wakings.
Total Sleep (24h) = estimated sleep + total nap minutes.
Sleep Efficiency = estimated sleep ÷ time in bed.
Habit Score (0–100) combines efficiency, wakings, latency, screens, caffeine, exercise, consistency, and quality rating. It is a tracking heuristic, not a diagnosis.

Because sleep varies, the score is designed for comparing days and spotting patterns.

FAQs

1) Is the habit score a medical diagnosis?

The score is a simple tracking indicator. It helps compare days and spot routine changes. It cannot diagnose sleep disorders or medical problems.

2) How does the calculator handle bedtime after midnight?

It assumes wake time may occur the next day. If wake time is earlier than bedtime, it automatically adds a day for the time difference.

3) What if my baby wakes for feeding often?

Log the number of wakings and an average duration. The tool will estimate awake time and efficiency. Feeding needs vary by age and growth stages.

4) Do naps count toward recommended sleep?

Yes. Many babies and toddlers get a large portion of sleep from naps. The calculator totals estimated night sleep plus naps within 24 hours.

5) Why include screen time and caffeine?

Both can delay sleep onset and reduce sleep quality. Tracking them helps you notice patterns, especially for parents, teens, and pregnancy routines.

6) What sleep efficiency should I aim for?

For many people, 85% or higher is a helpful target. Lower values can suggest long settling time or frequent awakenings, not always a problem.

7) How can I improve bedtime consistency?

Choose a realistic bedtime and keep it within 30–60 minutes most nights. Use the same wind-down steps, lighting, and room temperature.

8) When should I seek professional help?

Seek support if sleep issues persist for weeks, affect daytime function, or include breathing pauses, severe snoring, or safety concerns. Pregnancy sleep troubles can also need medical advice.
