Here’s the full list of holidays and observances in October 2023

Mark your calendars! Find something to celebrate every single day leading up to Halloween.

When you think of October, Halloween is often the first thing that comes to mind — and understandably so.

The last day of the month is a real treat (pun very much intended), but don't let the excitement surrounding the spooky season's standout trick you into thinking it's the only October holiday worth celebrating. In fact, there are tons of official (and unofficial) holidays, observance and awareness months from now through October 31.

Embrace all the food and fun that the season has to offer with holidays like National Pumpkin Day and National Apple Day. Or satisfy your sweet tooth before you get your candy fix on National Homemade Cookies Day, National Cinnamon Roll Day and National Dessert Day. (But since life is all about balance, don't forget to celebrate National Kale Day and National Oatmeal Day, too.)

It's not just about the treats, though: October is also a time to pick up some healthy habits that you can carry with you in the months ahead, whether it's clearing out your inbox (Inbox Zero Day) or finding an organization to volunteer for (Make a Difference Day).

Speaking of health, carve out time to raise awareness for important causes, ranging from mental health (World Mental Health Day) to menopause (World Menopause Day). All month long, wear your pink ribbon with pride and encourage loved ones to book their mammogram appointments in honor of Breast Cancer Awareness Month.

The list goes on — and on. Lucky for you, we've created a list of all the important dates in October, so you won't miss a thing.
