If you've spent any time in cannabis culture, you know 4/20 like the back of your hand. But there's another date circled on every concentrate lover's calendar: July 10th, better known as Oil Day. Less mainstream than 4/20 but just as beloved by connoisseurs, Oil Day is the annual celebration of everything dabbable — oils, wax, shatter, resin, and rosin. Here's everything you need to know about where it came from, why it matters, and how to celebrate it right.

The History Behind Oil Day

The story of Oil Day starts with a simple visual trick: flip the number "710" upside down, and it reads "OIL." That clever bit of numerical wordplay is exactly why July 10th (7/10) became the unofficial holiday for cannabis concentrates.

The term first started popping up online around 2010, gaining traction within cannabis forums and message boards frequented by concentrate enthusiasts. Rapper Taskrok is widely credited with helping popularize the term, having released an album on July 10, 2011, packed with tracks referencing cannabis oil. From there, the idea spread through underground and online cannabis communities who were eager for a day to celebrate concentrates specifically, separate from the flower-focused 4/20.

Oil Day really broke into the mainstream in 2013, when outlets like LA Weekly began reporting on it, and Denver hosted the first official 710 Cup that same year. Since then, Oil Day has grown steadily alongside the rise of legal cannabis markets, with dispensaries, brands, and events all leaning into the holiday every July.

Why Oil Day Matters

While 4/20 celebrates cannabis in all its forms, Oil Day zeroes in on something specific: the art and science of extraction. Concentrates like shatter, live resin, rosin, and vape oils represent some of the most technically advanced products in the cannabis space, often reaching THC levels far beyond traditional flower.

Oil Day gives that craftsmanship its own spotlight. It's a day to appreciate the extraction artists and brands pushing potency, purity, and flavor forward, and to recognize how far concentrate technology has come in just over a decade. For many enthusiasts, Oil Day is also a moment of community: a time to swap concentrates, compare terpene profiles, and geek out over the finer details of dabbing culture with fellow fans.

It's worth noting that Oil Day is still considered a niche, community-driven holiday rather than an official one — nobody owns it, and there's no single "official" origin story. That grassroots, born-from-the-community feel is part of what makes Oil Day special.

How to Celebrate Oil Day

Ready to mark Oil Day the right way? Here are a few ways enthusiasts typically celebrate:

• Try a new concentrate. Oil Day is the perfect excuse to branch out — pick up a live resin, rosin, or badder you haven't tried before and compare it to your usual go-to.

• Upgrade your setup. Whether it's a new dab rig, e-nail, or a simple dab pen, Oil Day is a popular time to refresh your gear.

• Start small if you're new. If you're newer to concentrates, begin with a dab about the size of a grain of rice and go slow. Oil Day is a great time to safely introduce a friend to dabbing for the first time.

• Compare terpene profiles. Concentrates are often described like fine wine, with subtle flavor differences between batches and extraction methods. Take the time to really taste what you're consuming.

• Shop the deals. Dispensaries and brands roll out some of their best concentrate promotions of the year on Oil Day, making it a great time to stock up.

However you choose to celebrate, Oil Day is really about honoring the craftsmanship behind concentrates and connecting with a community that geeks out over the details as much as you do.
