July 30 Holidays

International Day of Friendship was proclaimed by the UN General Assembly in 2011 to promote the idea that friendship between peoples, countries, and cultures can inspire peace efforts and build bridges between communities — observed on July 30 with shared activities, events, and cultural exchanges. National Cheesecake Day celebrates the dessert whose modern American form — cream cheese, sugar, eggs, and vanilla baked in a graham-cracker crust — is descended from the ancient Greek honey-and-wheat cake served to athletes at the first Olympic Games. National Father-in-Law Day was created to encourage people to express appreciation for the fathers of their partners — a relationship that is the subject of more jokes than gratitude. National Intern Day was established to celebrate the interns who work in organizations in exchange for experience, mentorship, and the occasional free lunch. Friendship, cream cheese, an awkward dinner table, and an unpaid contribution.
