A beautiful Chinese lunar calendar, one click away
Click the toolbar icon (or press Alt+Shift+K) to see lunar dates, solar terms, holidays and make-up workdays and the daily almanac. Events and lunar birthdays stay on your device and can sync to Google Calendar.
Why this extension
Checking holiday schedules, lunar dates or the almanac usually means a web search. This extension puts a full lunar month view in your toolbar — no new tab, no search. It works offline, collects no usage data, and keeps your events in your own browser by default.

Features
Month view at a glance
Monday-first 6×7 grid, big dates with lunar sub-labels, today and the selected day outlined in blue — the whole month on one screen.
Lunar dates, terms, festivals
Lunar calendar 1900–2100, solar terms on the day they begin, traditional and modern Chinese festivals.
Days off & make-up workdays
Pink “休” days off and “班” make-up workdays; the holiday menu jumps straight to the first day off.
Daily almanac (黄历)
Plain-language 宜 / 忌, plus pillars, spirits, day officer, lunar mansions, Peng Zu taboos and the twelve hours.
Events & lunar birthdays
All-day or timed events, daily to yearly repeats and lunar-yearly repeats that handle short months.
Western & custom holidays
Toggle Valentine's, Mother's Day, Halloween, Thanksgiving… or define your own by date, nth weekday, lunar date or solar term.
China / US modes
Switch to US mode for federal holidays (with observed days) and Sunday-first weeks — or show both sets at once.
Google sync, local first
Events live in IndexedDB; optionally push them one-way to a dedicated Google calendar that never touches your other calendars.
Made for
Planning around holidays
See every day off and make-up workday, with a countdown to the next holiday.
Lunar birthdays
Family birthdays on the lunar calendar convert to the right date every year — and sync to your phone.
Picking an auspicious day
Check the almanac before moving, opening a shop or a wedding.
Chinese diaspora in the US
Never miss Spring Festival or Mid-Autumn while seeing US federal holidays too.
Work planning
Event dots on a month view keep milestones and trips in sight.
