In Polish one word can't be use.
It should be 3 groups:
First
1 week = 1 tydzień

Second
2 weeks = 2 tygodnie
3 weeks = 3 tygodnie
4 weeks = 4 tygodnie

Third
5 weeks = 5 tygodni
...
30 weeks = 30 tygodni
...
100 weeks = 100 tygodni
and so on

For now, just use "tygodnie" which is the most common. I know it will look weird in some cases. I will be fixed in the future.
