The 'No Post on Sundays' meme originates from the 2001 film Harry Potter and the Sorcerer's Stone, featuring Richard Griffiths as the grumpy yet briefly jubilant Uncle Vernon Dursley. In this scene, Vernon celebrates the fact that no mail is delivered on Sundays, believing it will stop the relentless flow of Hogwarts acceptance letters. However, his victory is short-lived as hundreds of letters eventually explode through the fireplace. On the internet, the template is used to represent a fleeting moment of peace, a refusal to deal with work or stress during the weekend, or the ironic celebration of a temporary solution that is destined to fail spectacularly.
