About

Type Koyomi is a koyomi, the traditional Japanese calendar, with every day set in its own Japanese typeface. Each page shows the date with the moon, the season, the day's fortune, and any holiday, as the old almanacs did.

Features

How It's Made

The almanac comes from NASA JPL's DE440s ephemeris for the moon and the solar terms, and from the national holidays published by Japan's Cabinet Office. Every ink keeps a contrast of at least 4.5:1 on every paper. Every typeface is open source and credited to its designers.

Accessibility

VoiceOver reads each page as one description, from the date to the day's fortune. Text scales with Dynamic Type, and motion follows Reduce Motion.

Screenshots

Full-size iPhone and iPad screenshots, in English and Japanese, are in the press kit.
