Simple Calendars is made by two people who take birthdays very seriously.

It started with a problem we kept running into: the good moments are worth anticipating, and almost nothing online treats them that way. A birthday is a single push notification. An anniversary is a calendar alert. A wedding is a Google Doc. So we built a small app that turns the week or month before a moment into part of the gift — seven to thirty-one doors, each opening on its own day, each holding a note, a voice memo, a photograph, or a song.

Simple Calendars is for anyone who has ever wanted a little more time to tell someone what they mean. We think of it as a long-form card. You spend ten minutes filling it. They spend a week opening it. Somewhere in the middle, day six shows up when they're commuting and you accidentally make them cry on the train.

The aesthetic is deliberate — warm paper, a terracotta accent, serifs where we can get away with it, a little marginalia in pencil. Nothing about a personal calendar should feel like a SaaS dashboard. The pricing is deliberate too: you pay once, when the calendar is ready to send. No monthly drip. No subscription cage. Five dollars for the single gift you're making right now; a yearly plan if you're the sort of person who ends up making a lot of them; a lifetime plan if you already know.
