The Garfield Birthday Comic Zodiac is a popular internet subculture where individuals look up the specific Garfield comic strip published on the day they were born to serve as their personal 'zodiac sign.' This trend originated in online communities like Tumblr and Twitter, where users realized that the long-running nature of Jim Davis's strip (since 1978) meant almost everyone alive has a unique birth-strip. The meme is celebrated for its 'existential relatability,' as users often find that the specific humor or apathy of Garfield on their birthday perfectly mirrors their own personality. It has transitioned from a simple search-and-share activity into a creative meme format used to highlight the absurdity and unexpected wisdom found in decades of lasagna-related hijinks.
