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.
