End of week countdown

By the end of the day I will have 13 working days left before I'm NEET, "don't you mean 15 working days since today is the 10th of August and there's still 3 full weeks to go until the 31st?" No my unsuspecting fellow, there's a public holiday next Friday and I'm taking the Thursday off so I have 13 days of working left! and that means I'm going to have a 4 day weekend *glee*
