Migraine flare frequency calculator
How often are your migraines, really? Enter the number of headache days from your diary and the period they cover — this free calculator converts that into a monthly flare rate and shows it in context of the frequency thresholds clinicians commonly reference. No account, nothing leaves your browser.
Enter your flare days to see your monthly frequency. Count days from your own diary — the TrueTrigger dashboard counts them for you.
This calculator describes the frequency in your own records. It is not a diagnosis — frequency classifications are general reference points, and your doctor may classify things differently based on your full history.
Tracking beats calculating
A one-off number is a snapshot. TrueTrigger keeps a running headache diary — daily 10-second check-ins, trigger tracking, and a doctor-ready report — free, no account.
