Tracking the days since your last migraine
How to use a count-up counter for days since your last migraine, keep a record of attack dates, and bring real numbers to your next appointment.
If you get migraines, you know the question that opens every appointment: how many headache days did you have last month? Most people guess, and most people guess badly. A count-up counter fixes half of that problem, but only if you set it up so that resetting it does not erase the history you came to report.
TL;DR
Create one count-up event for “days since last migraine,” and every time you reset it, write the date down first. The counter gives you today’s gap. The list of dates gives you the monthly frequency your clinician actually asks about. A day counter is a frequency tracker, not a symptom diary, and confusing the two is why most tracking attempts fall apart by month three.
What the number tells you, and what it doesn’t
A “days since” counter answers exactly one question: how long has it been since the last attack. That is genuinely useful, for three reasons.
It is honest. Memory compresses bad stretches and stretches out good ones. A number that says 23 is not negotiable.
It is visible without effort. A counter on your home screen updates whether or not you open anything, which means it survives the weeks when you have no energy for tracking.
It reframes the good runs. In the middle of an attack it feels like it has always been like this. A counter is a small piece of evidence that it has not.
What it cannot tell you is almost everything else: how many attacks you had last month, how long each one lasted, how bad they were, what you took, what else was going on. Those are diary questions, and a single number cannot hold them.
The reset problem
Here is where most people lose their data. An attack happens, you open the app, you change the date to today, and the number you were carrying disappears. Six months later you have a counter that says 4 and no record whatsoever of the previous 180 days.
The fix is a two-step reset. Before you change the date, write down the date of the attack. Then reset. That is it. The list of dates is the real record, and the counter is the live readout on top of it.
Keep the list wherever you will actually keep it: a single note on your phone, a spreadsheet, or the back page of a paper planner. If you want everything inside one app, Day Counter supports unlimited events, so you can add a separate dated event per attack and let them stack up as an archive. Be warned that this gets noisy after a few months, so most people are better served by one counter plus one plain note.
Setting it up
1. Create the count-up event
Add a new event, choose the count up mode, and set the date to your most recent attack. Name it plainly. “Days since migraine” is fine. Add an emoji if you want it to feel less clinical.
2. Decide what counts as an attack
This is the decision that determines whether a year of data is worth anything, and it takes one minute. Does a mild headache you worked through count? An aura with no pain? A day you caught early with medication and mostly got away with? There is no correct answer, but there is a wrong one, which is deciding it fresh each time.
Write your rule at the top of your list and keep it consistent. Inconsistent counting is the single most common reason tracked data turns out to be useless.
3. Build a reset ritual you can do at 20 percent
Do it when the attack is over, not during it. Three fields is the most anyone sustains long term:
- The date (or date range, if it ran across days)
- Rough duration
- Whether you used acute medication
Thirty seconds, then reset the counter.
4. Add a monthly reminder
Set a reminder for the first of the month to count last month’s attack days and write the total next to the month name. This is the step that turns a scattered list of dates into the one number an appointment needs. Without it you will be counting backwards through a note in the waiting room.
5. Think before you add the widget
A home screen widget is what makes most counters stick, and for some people that is exactly right here too. For others, a permanent headache counter keeps migraine in the foreground of a day that was going fine. Try it for a week. If it helps, keep it. If it does not, the counter still works perfectly well inside the app.
Turning dates into numbers your clinician can use
| Number | How to get it | Why it is worth having |
|---|---|---|
| Headache days last month | Count the distinct dates in your list | This is the standard way frequency gets measured |
| Acute medication days last month | Count the dates where you noted medication | Clinicians watch this alongside attack frequency |
| Longest gap this year | The biggest jump between two consecutive dates | Shows whether the trend is moving |
| Current gap | Read it off the counter | Context for today’s conversation |
Headache specialists draw a line at 15 days. Fourteen or fewer headache days a month is classed as episodic migraine; 15 or more for longer than three months, with migraine features on at least eight of them, meets the ICHD-3 definition of chronic migraine. You are not diagnosing yourself with a phone app, and nothing here is medical advice. The point is narrower than that: the line is drawn using a count of days, so walking in with an actual count is more useful to your clinician than “a lot, I think.”
The same goes for medication days. How often you reach for acute treatment is something clinicians ask about specifically. Record the days, bring the number, and let them interpret it.
When a day counter is the wrong tool
When you are hunting for triggers. Sleep, stress, cycle timing, weather, food: none of that fits in a counter. Use a proper headache diary. The American Migraine Foundation’s guidance on headache journals covers what to record and how much detail is realistic.
When attacks are frequent. If you are getting several a week, the gap counter sits at 0 or 1 permanently and does nothing except tell you so. Track monthly totals instead and skip the live counter entirely.
When the number starts to hurt. This is the important one. A sobriety counter resets because of a decision. A migraine counter resets because of your nervous system, and treating a reset as a personal failure is both wrong and corrosive. If you find yourself dreading the reset, or feeling like you lost something, delete the counter and keep the list. The record is what has value. The streak was never the point.

FAQ
Should I log the day an attack started or the day it ended? Pick one and stay consistent. Most people log the start date, since that is what the gap between attacks measures. If an attack runs across two or three days, note the full range so your monthly headache day count stays accurate.
Does resetting the counter delete my history? Resetting changes the start date, so the previous number is gone from the screen. That is exactly why the write-it-down-first habit matters. Day Counter lets you edit event dates at any time, so a mistaken reset is easy to undo.
Is a counter a substitute for a headache diary? No. A counter tracks frequency and gaps. A diary tracks severity, duration, symptoms, medication, and possible triggers. If your clinician asked for a diary, keep the diary. The counter is just the number you can see without opening anything.
