National Days/Weeks #41

Last week's photos:
December 12 – Poinsettia Day
December 12 – Gingerbread House Day

Each week on Monday I'll post two photos which represent a "national day" or "national week" for the coming week [through the following Sunday].  Your job is to figure out which national day or week is depicted in each photo.  

Here are the photos for this week.  What national day or week does each represent?  Even if you're not 100% sure, make your best guess!  Come back next week to see if you're right.
