See May 2024's Full List of Holidays and Observances

April showers bring May flowers, as they say, so bring on the blooms! While May might not quite be the official start of summer (that's one of June's important dates), it sure feels like it. Schools let out for summer vacation, high school and college grads receive their diplomas, and mother figures get their day in the sun. May is a fun-filled month full of big events. Plan ahead by checking out our list of May 2023 holidays and observances, and be sure to mark the official holidays and unofficial national days of celebration on your calendar.

May Day rings in the month on May 1 with baskets of goodies and spring cheer. Cinco de Mayo, as the name implies, falls on the fifth of May, so start scoping out traditional Mexican recipes for the perfect food-fueled fiesta. Let’s not forget about Mother’s Day on May 14th. Honor all the motherly figures in your life — from new mothers to stepmothers — with gifts they’ll love. Of course, we had to include quirky holidays as well, such as National Burger Day (May 28) and National Mint Julep Day (May 30). They are backyard BBQ staples after all, and May is the month to dust off your grill and cook up some of the best grilling recipes.

Take special note of May’s health-related holidays, and place your well-being at the forefront. Book an appointment with a dermatologist for Melanoma Monday on May 1. Move your body with a fun workout on National Fitness Day on May 6, and be sure to check your blood pressure on World Hypertension Day on May 17.

The monthly observances in May include Arthritis Awareness Month, Better Sleep Month, Mental Health Awareness Month, National Walking Month, and Women’s Health Care Month. Self-care is always in style! May is also Asian American and Pacific Islander Heritage Month, and Military Appreciation Month.
