The occasion marks the 1932 decree, issued by King Abdulaziz, which renamed the Kingdom of Hejaz and Nejd to the Kingdom of Saudi Arabia.
It is a time for celebration, and friends and families will gather and exchange gifts all themed around the colours of the national flag — green and white. So it's time to treat someone you love, or even yourself.
If you're looking for something small to give, how about an eyeshadow? MAC Cosmetics offers a metallic green-black option in its Duochrome range.

And for something a little more substantial, Balenciaga has wrap-around sunglasses with twin Bs picked out in gold.
Gucci's Flora Gorgeous Jasmine fragrance comes in a pretty retro style bottle, decorated with florals on a ground of turquoise. Heavy with the sensual scent of grandiflorum jasmine, this is perfect for those who love the intoxicating scent of fresh evening jasmine.
Jewellery fans will love the multi-coloured gemstone drop earrings by Dolce & Gabbana that are a melange of pretty pastel shades, while someone who prefers something a little more dainty should look for 18ct gold and gemstone stud earrings from Maria Tash.
Another way to wear jewellery is on shoes, such as the clear green kitten heels by Amina Muaddi. With its signature pyramid heel and dazzling buckle, these are perfect for stepping out.
Sneakerheads will love DSquared's multicoloured trainer, which has an air-filled sole and comes in rust, mustard, lilac and pistachio colours. The new Bottega Veneta pillow trainer, meanwhile, with its plumped sole, can be found in a vibrant shamrock green.

Finally, an easy way to add a dash of green into anyone's wardrobe is via a bag, and this season there are plenty of options.
Stella McCartney's small Frayme puffy bag comes in a charming shade of pale mint, while the Loewe Puzzle bag can be found in a punchy forest green.
