Opis
Lately, we have in Warsaw two main types of quiz caches: those, where the task is to find some information and other ones, where we have to understand what the author had in his mind J Some of them are quite malicious, like for example this one. Such quiz caches, where the aim is to count something connected with a practical problem appear rarely. What kind of problems are we particularly interested in ? For example, if we go to work on some day or not, aren’t we ?
As we know, most of us work from Monday till Friday and we have free Saturdays and Sundays. Apart from that, we have 20 or 26 holidays and theoretically 13 national holidays. But that is only theoretically, because some of those 13 days are on Sundays every year (like first day of Easter) and others are sometimes also on Sunday, depending simply on the order of the weekdays each year. For example, at the end of 2016 and beginning of 2017 we had a rather poor situation, because out of 3 days, which should theoretically be free, we had actually only 1 extra free day, because other 2 were on Sunday anyway.
If a national holiday is in some year on Saturday, according to the law, our employer has to appoint an other extra free day. But not if a national holiday is on Sunday. So actually, we have in practice a bit less than 13 free days every year. How much exactly ? This is what we have to count. How to do this exactly ?
1. We take under consideration all years of 21st century, so from 2001 till 2100. Probably not many of us will live until then, and for sure nobody will work for the whole 100 years, but we have to make some assumptions 
2. We also assume, that during those 100 years all the time we have those 13 national holidays. That is actually not exactly true, because for example the feast of the Epiphany began to be a public holiday a bit later. And also we don’t know if some other free days will appear till 2100, but we don’t care about it now.
So our aim is to count how many public holidays do we averagely have during this period (so we count only those days, which are not on Sundays each year). We should get a number with one decimal place. We note it as AB,C and we count the coordinates of the cache:
52 12.100*C+10*B+5*A-52
20 54.40*B+20*A+9*C+11
