Lesson 8 · Foundational Components

Moon, Sky, Year: 月 / 天 / 年

With all ten digits in hand since Lesson 6, three more characters are enough to read and write full dates: 月 (yuè, "moon, month"), 天 (tiān, "sky, day"), and 年 (nián, "year").

月 is a pictograph of a crescent moon — but watch for a famous lookalike. When 月 sits inside or beside another character, it's sometimes not "moon" at all: ⺼, the body-part radical derived from 肉 (ròu, "flesh, meat"), is written essentially identically to 月 in modern script. 背 (bèi, "back") and 肝 (gān, "liver") both contain the meat version, not the moon. You generally can't tell which one you're looking at just by sight — only by knowing the character — so the takeaway is "if it's a body part, guess meat; otherwise, guess moon," not a hard rule. (Wiktionary: 月)

天 decomposes — it's Lesson 3's 大 with one stroke added on top:

天tiānsky, heaven, day

一+大=天

A person (大) with a line above their head — what's above a person is the sky. (Wiktionary: 天)

年Wiktionary traces 年's history through 禾 ("grain," later taught in Lesson 17) plus a phonetic stand-in for 人 ("person," Lesson 1), from an original meaning of "harvest" that shifted to "year" since harvest comes once a year. But centuries of clerical-script evolution mean the modern 年 doesn't visibly contain either piece anymore.

Stroke order

天 reuses 大's order from Lesson 3, with the new top stroke written first (top-to-bottom):

天 — 4 strokes
▶ watch animated

月 — 4 strokes

Outer frame before inner strokes. 月's left side is a 撇 (slightly angled), not a straight vertical — worth noting for handwriting:

月 — 4 strokes
▶ watch animated

年 — 6 strokes

年 — 6 strokes
▶ watch animated

Examples using these components: today's date

月 paired with Lesson 1's 日 gives one of the most-loved characters in the language:

明míngbright

日+月=明

The sun just risen and the moon not yet set — dawn, the first light of the day. (Wiktionary: 明)

明 plus today's 天 gives you an everyday word, useful for any travel planning:

明天míngtiāntomorrow

明+天=明天

Literally "bright day."

And with every digit from Lesson 5/6 plus 月 and 日, you can read or write any month-and-day date:

六月二十四日liù yuè èr shí sì rìJune 24th

Literally "six-month, two-ten-four-day."

年 slots in front of a number the same way, for the year — though in practice, most real-world signage mixes scripts and just writes the year in Arabic numerals before 年 (2026年) rather than spelling it out in characters.

Etymology sources for every character above are linked inline. For the rigorous version of any of them, see the Outlier Dictionary of Chinese Characters.

Out in the world: dates are everywhere you'll need to read — train and flight tickets, hotel bookings, opening hours, expiry dates. Try reading the month-and-day portion of any date you next encounter in characters before checking the Arabic-numeral version next to it.
