Example Data Table

This sample shows how diary entries can reveal daily patterns, target speed, and changes from a typical hourly rate.

Date	Session	Duration (h)	Total Moves	Moves/Hour	Target %	Status
2026-03-04	Morning Check	2.00	11	5.50	110%	Target reached within expected window
2026-03-05	After Lunch	1.50	10	6.67	100%	Target reached within expected window
2026-03-06	Evening Check	2.00	7	3.50	70%	Below target after full window
2026-03-07	Bedtime Review	1.75	13	7.43	130%	Target reached within expected window

Formula Used

This diary turns one observation session into measurable indicators that make patterns easier to review over time.

Core calculations

Observation Duration = End Time − Start Time
Movements per Hour = Total Movements ÷ Duration in Hours
Average Minutes per Movement = Duration in Minutes ÷ Total Movements
Target Completion % = (Total Movements ÷ Target Movements) × 100

Advanced indicators

Weighted Activity Score = (Flutter × 1.0 + Rolling × 1.2 + Strong × 1.5) ÷ Duration in Hours
Estimated Target Time = Target Movements ÷ Movements per Hour
Baseline Change % = ((Current Hourly Rate − Usual Hourly Rate) ÷ Usual Hourly Rate) × 100

These formulas do not diagnose anything. They organize observations so discussions with a clinician can be clearer and more consistent.

Frequently Asked Questions

1. What does this baby movement diary calculator do?

It records one observation session and calculates duration, movements per hour, average interval, target progress, and simple comparison measures for clearer tracking.

2. Does this tool replace medical advice?

No. It is only a tracking aid. If movements feel suddenly reduced, absent, or very different from your usual pattern, contact your maternity care team promptly.

3. Why enter strong, rolling, and flutter movements separately?

Separate counts create a richer diary entry. They help you describe the session better and generate the weighted activity score used in the summary.

4. What is the weighted activity score?

It is a simple intensity indicator. Flutter, rolling, and strong movements receive different weights so you can compare session character, not just movement quantity.

5. Why compare with a usual hourly rate?

A baseline rate helps show whether the current session is tracking close to your typical pattern or looks lower or higher than normal.

6. Can I use a different target than ten movements?

Yes. The calculator lets you set your own target count and time window so the diary matches the guidance you follow.

7. What if my session crosses midnight?

The duration logic supports overnight sessions. If your end time is earlier than the start time, the calculator treats it as the next day.

8. What do the export buttons save?

CSV saves key result fields for spreadsheets. PDF saves a formatted diary summary that is easier to print, archive, or share during appointments.
