At a school with a block schedule Second Friday is either the actual Friday of the week or Thursday if Friday is a day off. This is because the students don't have their classes on that day until the next week.
Second Friday is the best Friday because I don't have to see my teachers until next week.
At schools with a block schedule, Third Friday is only present if Friday is a day off. It is the actual Friday of the week, because Wednesday is the last day you have one set of classes then Thursday is the last day you have the other set of classes, and then there is the real Friday.
If Thursday and Friday are both days off there are still only three possible Fridays (because Thursday is more like a first Saturday); although, First and Second Friday are moved back one day... Third Friday can also be called "normal Friday" or just "Friday."
At a school with a block schedule the first Friday of the week is Thursday, because it is the last day that you do those classes for the week. The Friday after that, or Second Friday, is the normal Friday of the week. If Friday is a day off then Wednesday becomes First Friday, Thursday becomes Second Friday and Friday either stays Friday or becomes Third Friday.
Happy First Friday!
Man, I'm so glad it's First Friday. That means I don't have math class until Monday!
