Chinese Almanac Yi Ji Guide: Reading the Daily Columns

A Chinese almanac, often printed as a single page for the home and known in Cantonese-influenced usage as the huangli, packs a day's worth of traditional information into a few columns: the lunar date, the day's stems and branches, the solar term it belongs to, the activities it is said to favour (yi) and to discourage (ji), the animal sign it clashes with and the direction of that clash, and the deity assigned to the day. Most people read two or three of those columns and ignore the rest, which is a reasonable way to use it, provided they know what the columns do and do not claim. This guide explains each one with dates from 2027 that can be checked directly.

The almanac is a daily table, not a yearly one

The first thing to understand is the unit of the table. A Chinese almanac is not a list of auspicious dates for the year; it is an entry per day, and each entry describes that day within a cycle. The cycle is the sexagenary one, sixty combinations of ten stems and twelve branches, and it repeats without regard to the month or the year.

That is why the entries cannot be reused. A day with a given stem and branch pair comes round every sixty days, and the surrounding days differ each time, so a page copied from last year describes different dates. The same is true of printed almanacs sold each year: the format is identical, the content is not.

The almanac also carries the lunar date and the solar term for each day, which is what makes it useful for festivals. The festival side of the calendar is covered in the Chinese lunar calendar 2027; the columns described here sit alongside it on the same page.

Reading the yi and ji columns

Yi means fitting or appropriate, and ji means taboo or to be avoided. In practice the two columns list activities: a wedding, moving into a new home, breaking ground, opening a business, travelling, bathing, sweeping, having a burial.

The lists are not adjectives. A day is not declared good or bad as a whole; it is declared suitable for some activities and unsuitable for others. This distinction matters because it is the one most often lost in retelling. Someone who says "the almanac says Tuesday is bad" has usually read one column and skipped the other.

The length of the lists varies enormously from day to day. Some days carry a long yi list and a short ji list; others the reverse. A long ji list does not make the day unusable, and a long yi list does not make it uniformly favourable. The lists are a summary of what the source text records for that day's position in the cycle.

The clash and the direction

The clash column names an animal sign. The twelve branches are arranged in opposite pairs, and the branch of the day sits opposite one of them: the rat is opposite the horse, the ox opposite the goat, the tiger opposite the monkey, the rabbit opposite the rooster, the dragon opposite the dog, and the snake opposite the pig.

When a day's branch is opposite a sign, the almanac prints that sign as the clash, together with the stem and branch of the specific day that will be clashed. For 6 February 2027, New Year's Day, the day pillar is Bing Chen, a dragon day; the printed clash is therefore the dog, named in full as Geng Xu. The Mid-Autumn Festival, 15 September 2027, is a Ding You day, a rooster day; its printed clash is the rabbit, given as Xin Mao. The clash records a relationship between the day's branch and the twelve signs, and it is a calendar fact rather than a statement about individuals.

The direction printed with the clash is the direction traditionally treated as unfavourable on that day, and it follows a fixed pattern tied to the day's branch. On 6 February 2027 the direction is south. On 15 September 2027, the Mid-Autumn Festival, the clash is with the rabbit and the direction is east.

What the clash does not mean is that people born under the clashing sign should avoid the day. That reading is a modern simplification. Traditional use treats the clash as one of several day markers, and the practical advice attached to it concerns the direction, not the person.

The day deity and the two paths

Each day is assigned one of twelve deities. Six belong to the Huangdao group, the yellow path, which is treated as auspicious; six belong to the Heidao group, the black path, which is treated as inauspicious. The names are symbolic: Jinkui, the Golden Casket, and Yutang, the Jade Hall, are Huangdao; Xuanwu, the Black Tortoise, is Heidao.

The labels are summary indicators. A Heidao day is not forbidden, and a Huangdao day is not guaranteed. The activity lists remain the detailed part of the entry, and the group label is a shortcut for readers who want one word instead of a list.

Two examples show how the columns sit together. New Year's Day 2027, 6 February, is governed by Jinkui and is a Huangdao day; its yi list includes weddings and travel, its ji list includes moving house, stove work, medical treatment and burial. The Mid-Autumn Festival, 15 September 2027, is governed by Yutang, also Huangdao; its yi list includes offerings, travel, bathing and sweeping, and its ji list includes breaking ground and buying property. A day such as 1 July 2027 shows the other case: Xuanwu, a Heidao deity, with the day marked as inauspicious in the group column.

How to read a day's entry in order

Read the lunar date first, because it tells you what the day is in the festival calendar and whether anything is being observed.

Read the stems and branches next, since the clash and much of the yi and ji content follows from them. If you only note one thing from this column, note the day's branch.

Then read the solar term. It places the day in the season, and some activities in the lists are seasonally constrained. The terms and their dates for the year are collected in the 24 solar terms of 2027.

Then read yi and ji, scanning for the activity you care about rather than reading the list from the top. Most people are looking for one item: a wedding, a move, a signing, a journey.

Finally read the clash, the direction and the deity, in that order, and treat them as context rather than as a verdict.

To run through the same steps on a live page, open the daily Chinese calendar, choose the month, and select the day; all the columns appear together.

Common mistakes in using the almanac

The first is reading the yi list as permission and the ji list as prohibition. Both are recommendations from a tradition, and neither is a rule.

The second is treating a long ji list as a bad day. The lists simply record more discouraged activities, often because the day's position in the cycle carries more restrictions in the source text.

The third is reading the clash as a personal warning. It is a relationship between branches.

The fourth is using an almanac from a different country or a different school without knowing it. The yi and ji content varies between compilations, so a discrepancy of one or two activities is expected; only the date should match exactly.

The fifth is assuming the almanac applies to everyone in the household in the same way. Traditional use often weighs the day against the birth dates of the people involved, which is a separate exercise from reading the page.

The almanac is a compact reference for a traditional way of arranging time. It tells you what a given day is called in the lunar and sexagenary systems, what the tradition associates with it, and which direction it marks as unfavourable. It does not know your circumstances and does not claim to.

Used that way, it is a useful second opinion when a date has to be fixed and there is room to move it by a day or two. Used as an instruction, it produces the kind of anxiety that the tradition itself does not require. To check a day before deciding, open the Chinese calendar and read the entry for that date. For the parts of the page that concern birth dates rather than events, converting a lunar birthday covers the conversion and the year boundary that catches people out.
