Public transport Itinerary

When I arrive in Wroclaw, I saw the schedules of buses and trams, and didnt know how to use it, I fel awkward. Well, here in the photo you can see one, this specificity is about 406 which is the bus that go to the airport. There are several things to consider in these itineraries: 1 º) are 3 columns, the 1 st Monday till Friday, the 2 nd Saturday and 3 rd Sundays, keep in mind that if you go out at night on a Friday and return at dawn, you have to look at the column on Saturday (something so silly can suppose you lose the transportation). 2 º) on the top left of course puts the number or letter of the line3 º) above all it puts the name of the stop where we are right now4 º) on the left makes the journey from the bus stop where we are (the points with black shadow), and the minutes it takes to reach the following stops (as defined). 5 º) last but not least important, underneath it all, sometimes puts some letters (which appear in the list next few hours), these letters tell us whether at certain times makes a journey extraordinary (because it does another tour for any reason). Something as simple and silly, can save many difficulties and problems before coming to Wroclaw (these times in other Polish cities are the same).
