Swiping psychotically through Tinder after dinner each night of the holidays to kill time and ensure matches.
Alone in quarantine or bored stiff on their parents' couch, young singles everywhere swipe to the end of their daily allowance, reaping a heinous daily match with a past-prime hometown hottie, or the waiter from the cafe downstairs you've never seen with his mask off. Tinder Advent Calendar matches offer all the short-lived indulgence of the advent chocolates of childhood, but with the added risk of a dick pic.

A calendar that completely skips over July 1st and has June 32nd instead to avoid failing No Jerk July on the first day
by TheStupendousOne July 2, 2025

A math calendar à la Singapour, which is designed in such a way that the answer to the problem on each day is the date on which the question appears, aims to develop in children a positive attitude towards the world’s most disliked school subject—when they are exposed to the beauty and joy of math rather than seeing it as a mere drill-and-kill subject.
The Singapore Mathematics Calendar—which takes three or four times longer to write than a typical assessment (or supplementary) math title, and costs a few folds more in publishing it—is a first in Singapore math publishing, as it offers students a creative and fun way to learning math, while honing their problem-solving skills.

When an Airbnb host refuses to accept a booking request unless you extend it to fill a gap in their calendar
I tried to go on holiday, and I thought I found the perfect place until I tried to book it and the host turned around and tried to calendar gouge me.

In the bobistic calendar, you don't have any past or future. Yesterday? What's that? Tomorrow? What's that? What I ate this morning? What's a morning? You just have the present. And the present is in the year 202030. When was Jesus born? Jesus is born at 202030. When are the next elections? In 202030. What was the previous year? It was 202030. Next Year? Thats also 202030. Yesterday, tomorrow, next week? None of them exists. Only 202030.

Initially created to avoid having to say the term "groomer" (or relative terms such as "grooming") aloud when in the company of people, or in a place where you'd rather not have people hear you talking of such a topic. Especially when it comes to discussing the topic to someone who is easily triggered by the initial subject.
"Door-to-Door Calendar Salesman" is a code-term to use in place of a "child groomer."
"Selling calendars" means to commit the act of grooming.
"Going door to door" means they're searching for minors to groom.
"Asking a minor for calendars or photos of their calendars" means they're asking a minor for illegal sexual favours, or for sexually explicit photos of said minor.
Person A: "Have you heard that Onision has been going door to door and selling calendars?"
Person B: "What the fuck is up with that? Selling calendars...He should go to prison for it."
