A Change in Schedule

We have class this Saturday and Sunday, in order to get a week off for holiday. October 1st is "National Day". Typically this is a week long vacation, where most people travel back to their home in order to spend this week with their families. Since October 1st falls on a Wednesday, the whole country gets off from school and work Wednesday, October 1st through Sunday, October 5th. In order accommodate people and give them the flexibility to travel home, it is acceptable to work on Saturday and Sunday in order to get Monday and Tuesday off. Thus we have class on Saturday and Sunday, but have a week of vacation!
