## General Information
- Pesel number is 11 digits number given to citizens in Poland that allows for easy identification of a person who owns it (more info [here](https://www.gov.pl/web/gov/czym-jest-numer-pesel)).
- This app generates Pesel number in compliance with all the regulations accessible online on Government site.
- This project was my very first on the way to learning programming. Recently I refactored code and improved calculations of the Pesel also for the people who will be born in the 22nd and 23rd century.
## How the Pesel Number is calculated?
- All the resources I've been working with can be found here - available in [Polish](https://www.gov.pl/web/gov/czym-jest-numer-pesel) or alternatively in English on the website of [UOW](https://welcome.uw.edu.pl/during-your-stay/pesel-number/).
- Pesel number has fixed structure:
```
YYMMDDPPPPK
```
- YY - last two digits of a year person was born in
- MM - month
- DD - day
- PPPP - random number, but the last digit indicates person’s gender - odd number is for male, even – for female ( zero here is treated as even)
- K - control number
The adopted methodology for coding the month of birth allows for differentiation of persons born in 5 distinct centuries. The consecutive months in each century have the following numbers:
|Month |1800-1899 |1900-1999 |2000-2099 |2100-2199 |2200-2299 |
|-----------|:--------:|:--------:|:--------:|:--------:|:--------:|
|January |81 |01 |21 |41 |61 |
|February |82 |02 |22 |42 |62 |
|March |83 |03 |23 |43 |63 |
|April |84 |04 |24 |44 |64 |
|May |85 |05 |25 |45 |65 |
|June |86 |06 |26 |46 |66 |
|July |87 |07 |27 |47 |67 |
|August |88 |08 |28 |48 |68 |
|September |89 |09 |29 |49 |69 |
|October |90 |10 |30 |50 |70 |
|November |91 |11 |31 |51 |71 |
|December |92 |12 |32 |52 |72 |
The last 11th digit can be calculated in 3 easy steps:
1. All 10 digits have to be multiplied by consecutive weighs assigned to them: 1-3-7-9-1-3-7-9-1-3. Taking as example number 0207080362:
0 * 1 = 0
2 * 3 = 6
0 * 7 = 0
7 * 9 = 63
0 * 1 = 0
8 * 3 = 24
0 * 7 = 0
3 * 9 = 27
6 * 1 = 6
2 * 3 = 6
2. If result of multiplication is two digit number take as its result the last digit of the number. The individual results should be added e.g.
0+6+0+3+0+4+0+7+6+6=32
3. The result obtained by adding all the numbers should be then modulo'ed by 10. The number which we will get should be then subtracted from 10- the number obtained as a result is the control number. If the result of modulo by 10 is 0, then control number equals 0.
32%10=2
10-2=8
