National days: 18

Days until: 365

October 21 was made for an autumn movie night, with something crisp and sweet for the opening scene and a bubbling pan of cheese waiting for the feature.

Give National Apple Day the starring role. If a local orchard is within reach, go apple picking and bring home enough fruit for dessert. The wandering, choosing and occasional debate over the best-looking apple are part of the fun. Back home, bake your haul into a warm pastry. It can cool while you decide what to watch, provided nobody keeps wandering through the kitchen to inspect it.

National Apple Day

Gobble down an apple, make a delicious apple dessert or savory dish, or join an apple day event for food, games, activities and more during apple season.

For the savory half of the spread, pile a pan with crunchy chips and plenty of melted cheese for International Day of the Nacho. Set it where everyone can reach and accept that one chip will inevitably be holding up half the toppings. That chip belongs to the bold. If you are watching solo, you also get undisputed control of both the remote and the best corner of the pan.

International Day of the Nacho

A crunchy, cheesy snack that’s perfect for sharing with friends and family, whether you’re watching the big game or having a movie night!

Then start the movie, pass the nachos and save the apple pastry for the final act. October 21 does not need fancy table settings or a complicated menu. A couch, a cheesy crunch and the smell of baked apples have the evening covered.
