Key points
- Record the time bleeding starts and stops, not just the date: 3 days means 72 hours.
- Record clean days between bleedings, because gaps under 15 days are joined to the bleeding.
- Apps predict; they do not classify haiz and istihaza. Use the rules or a calculator for that.
Why tracking is part of worship
The rulings of haiz depend on numbers: 3 days, 10 days, 15 days, and your own habit. Without records you cannot know whether to pray, and mistakes can mean missed prayers or invalid fasts. Keeping a record is how you protect your salah.
What to write down
- Start and end with time. "Started Tuesday 10 pm, stopped Saturday 9 am." The 72-hour minimum and 240-hour maximum are counted in hours.
- Clean days. Any day with no discharge, including gaps in the middle of bleeding.
- Colour. Note when discharge turns pure white or completely clean: that is when haiz has ended.
- Ghusl and worship. When you made ghusl, which prayers you missed, and fasts to make up.
- Your current habit, updated after every cycle.
A simple monthly template
| Bleeding started | Bleeding ended | Clean gaps | Purity before | Ruling |
|---|---|---|---|---|
| 3 Mar, 22:00 | 10 Mar, 07:00 | none | 24 days | Haiz, 7 days 9 hours. Habit 7/24 |
Using period-tracking apps
Apps are useful for reminders and history. But most of them predict cycles from averages and label every bleeding as a "period". They do not know that bleeding under 3 days, over 10 days, or after less than 15 days of purity is istihaza. Use an app that lets you enter bleeding, spotting and clean days manually, and apply the rules yourself or with our Haiz Calculator and Taharat & Dam Calculator.
Choose apps that respect your privacy. Your cycle data is sensitive; the calculators on this site run in your browser and do not send your entries anywhere.
When to ask for help
If your bleeding is irregular for months, if you have forgotten your habit, or if your pattern is very complicated, ask a scholar with your records in hand. If bleeding is unusually heavy or long, see a doctor as well.
