This app counts 90 days of health insurance for unemployed people.
As a social worker I had to count 90 days from a day customer applied for health insurance. To do so I had to use table callendar and count these 90 days day by day in loud environment with coworkers chatting around :) As you can imagine it was very easy to make mistakes.
Counting 90 days took approx. 10 minutes if you were lucky and didn't have to recheck it :)
One day I decided to learn JavaScript and make a calculator which will count these 90 days for me.
So I did.
This is super-easy app but even my managers haven't seen something similar. We decided to share this app with other social institutions and it did work! I reveived a lot of positive feedback from institutions around whole Poland.
All you need to do is pick the starting date from browser's callendar and hit the "Oblicz" button (which means Count it).
Third navy/blue area from the top will display the proper date - the ninetieth day of insurance.
Hope you will enjoy it.
