Short Answer
The tracker adds the configured waiting period for the selected donation type to the reference donation date.
Detailed Explanation
The calculation begins with the Last Donation Date used by the tracker.
The tracker normally obtains this date from your most recent donation record. If no donation record exists, it uses today's date.
You can also enter a different date manually.
The system then applies the waiting period configured for your gender and the previous and next donation types.
For example, the code uses different intervals for platelet/plasma donations and whole-blood-related donations.
The resulting date is displayed in YYYY/MM/DD format.
Key Points
- The calculation starts from the selected reference date.
- Your latest recorded donation is normally used automatically.
- Today's date is used when no donation history is available.
- You can manually change the reference date.
- The waiting period depends on the donation-type combination and configured rules.
- The result is an estimated date.
❤️ Motivation
A clear donation schedule helps you plan your next opportunity to give while respecting appropriate waiting periods. ❤️
