Lu Lunar Calendar

A tear-off wall calendar for your phone. Each morning, yesterday tears away to reveal today's solar and lunar date, stems and branches, and the season.

Lu is a traditional Chinese tear-off calendar that lives on your phone.

The first time you open it each day, yesterday's page tears away and today appears: the solar and lunar dates side by side, the sexagenary stems and branches, the year's animal, the moon phase, and the next solar term.

• Today: tear-off page, lunar date, stems and branches, moon phase, the current solar term and its seasonal notes • Almanac (黃曆 宜忌): each day's traditional "suited" and "avoid" activities, from the 建除 rules, computed on your device. Turn it off in Settings if you don't want it • Month: solar and lunar dates in every cell, plus solar terms and festivals • 24 Solar Terms: exact times to the minute, grouped by season • Converter: solar ↔ lunar in both directions, to find a lunar birthday or festival date • Me and My Dates (我, 我的日子): save your own birthday and your family's birthdays, memorial days and anniversaries, lunar or Gregorian. Each year the app finds the date and can remind you. My Dates stay on your phone • Me also shows a reference table of your four birth pillars and the twelve palaces (traditional calendar reference). Our server builds it from your birth date, hour and gender under an anonymous account, so the first time needs a connection; after that it opens offline. Delete it any time in Settings • iPhone Duo: two panes on the inner screen in landscape; on the outer screen and in landscape, the tabs move to the side column • Widgets: lunar date with 宜/忌, moon phase and next solar term on your Lock Screen, Home Screen and in StandBy • Reminders: daily page, new and full moon, the eve of each solar term and festival, and your saved dates • Dark mode. Traditional and Simplified Chinese. No sign-up. The calendar is computed on your device and works offline. Anonymous usage statistics contain no personal data and can be turned off in Settings.
