This tracker supports personal monitoring and record keeping. It does not confirm a diagnosis. Seek urgent local support immediately if personal safety is at risk.
Example Data Table
| Start Date | End Date | Duration Days | Symptom Days | Severity | Impaired Days | Tracking Score | Label |
|---|---|---|---|---|---|---|---|
| 2026-02-01 | 2026-02-21 | 21 | 15 | 6.5 / 10 | 9 | 59.29 / 100 | Moderate tracked burden |
| 2026-03-01 | 2026-03-10 | 10 | 5 | 4.0 / 10 | 2 | 35.50 / 100 | Mild tracked burden |
| 2026-03-15 | Ongoing | 18 | 16 | 8.0 / 10 | 12 | 79.11 / 100 | Higher tracked burden |
Formula Used
Duration Days = (Effective End Date − Start Date) + 1
Symptom-Free Days = Duration Days − Symptom Days
Active Day Percentage = (Symptom Days ÷ Duration Days) × 100
Impairment Percentage = (Impaired Days ÷ Duration Days) × 100
Sleep Disruption Percentage = (Sleep Disruption Days ÷ Duration Days) × 100
Missed Day Percentage = (Missed Days ÷ Duration Days) × 100
Tracking Score = (Severity Factor × 35) + (Active Day Percentage × 0.30) + (Impairment Percentage × 0.15) + (Sleep Percentage × 0.10) + (Missed Day Percentage × 0.10)
Severity Factor is Average Severity divided by 10. The score is capped at 100. This score summarizes burden for tracking only. It does not diagnose any condition.

Frequently Asked Questions
1. What does this tracker calculate?
It calculates episode duration, symptom-free time, active symptom percentage, impairment percentage, sleep disruption percentage, missed day percentage, and a combined monitoring score.
2. Does the tracking score diagnose depression?
No. The score only summarizes the data you entered. It helps organize tracking trends and discussion points. It cannot diagnose depression or replace professional assessment.
3. Why count symptom days separately from duration days?
A long calendar span does not always mean symptoms happened every day. Separating symptom days from total days shows how concentrated or intermittent the episode felt.
4. What does longest symptom streak mean?
It is the longest continuous run of days with symptoms during the tracked period. It helps show persistence even when total symptom days stay unchanged.
5. Can I use this for an ongoing episode?
Yes. Mark the episode as ongoing. The calculator will use today as the effective end date and update duration-based percentages from that point.
6. Why export results as CSV or PDF?
CSV is useful for spreadsheets and long-term tracking. PDF is better for journaling, printed records, or sharing a clean summary during appointments.
7. How often should I update the tracker?
Daily or weekly updates usually work best. More consistent entries create clearer trends and reduce recall gaps when reviewing symptom patterns later.
8. When should urgent support be sought?
Seek immediate local emergency or crisis support if safety feels uncertain, self-harm risk appears, or basic daily functioning becomes suddenly unsafe.
