Chinese Date Formats In Traditional Chinese (日期格式 — Rìqí Géshì)

Dates are tiny time-capsules, and Mandarin labels them with a clean, left-to-right rhythm: year → month → day. Learn the standard written form, how people say dates out loud, Taiwan-specific quirks like the ROC year, and a few polite ways to ask and answer “what’s today?” in Traditional Chinese, with pinyin right after and natural English glosses.

The Core Pattern You’ll See Everywhere

The standard written order is Year 年 + Month 月 + Day 日/號. It’s wonderfully literal.

今天是二〇二五年十二月一日。
jīn tiān shì èr líng èr wǔ nián shí èr yuè yī rì
Today is December 1, 2025.

開會日期:2025年06月15日。
kāi huì rì qí: èr líng èr wǔ nián líu yuè shí wǔ rì
Meeting date: June 15, 2025.

票券有效至:2025年12月31日。
piào quàn yǒu xiào zhì: èr líng èr wǔ nián shí èr yuè sān shí yī rì
Ticket valid until: December 31, 2025.

Notes:
「日」 and 「號」 both mean “day of the month.” 「日」is more formal/printed; 「號」is common in speech.

How People Say Dates Out Loud

Spoken dates follow the same order, but with natural shortcuts.

今天十二月一號。
jīn tiān shí èr yuè yī hào
Today is Dec 1.

我們三月二十五號見。
wǒ men sān yuè èr shí wǔ hào jiàn
Let’s meet on March 25.

截止到七月三十一號。
jié zhǐ dào qī yuè sān shí yī hào
Deadline is July 31.

Year in speech: say each digit or chunk it as a whole number—both are understood.
二〇二五年/兩千零二十五年
èr líng èr wǔ nián / liǎng qiān líng èr shí wǔ nián
Year 2025.

Numeric Formats You’ll See In Forms, Tickets, Apps

YYYY/MM/DD → 2025/12/01
èr líng èr wǔ / shí èr / líng yī
2025/12/01

YYYY-MM-DD → 2025-12-01
èr líng èr wǔ – shí èr – líng yī
2025-12-01

YY/MM/DD (be mindful of century) → 25/12/01
èr wǔ / shí èr / líng yī
’25/12/01

No commas, month names, or day-month swapping—Chinese keeps the big→small order.

Weekdays And “What Day Is It?”

The weekday system is tidy: 星期+一二三四五六/日(天) or 週/禮拜 variants. Taiwan everyday usage often prefers 星期.

今天星期一。
jīn tiān xīng qí yī
Today is Monday.

禮拜天要不要聚餐?
lǐ bài tiān yào bù yào jù cān?
Want to get together on Sunday?

會議在星期三早上十點。
huì yì zài xīng qí sān zǎo shàng shí diǎn
The meeting is Wednesday at 10 a.m.

Taiwan’s ROC Year (民國年) On Government Things

Official forms and counters may use the ROC system: ROC 1 = 1912 CE. So CE − 1911 = ROC.

民國114年12月01日
mín guó yī bǎi yī shí sì nián shí èr yuè líng yī rì
Dec 1, 2025 (ROC year 114).

公式:西元年(CE)-1911=民國年
gōng shì: xī yuán nián (CE) − yī jiǔ yī yī = mín guó nián
Formula: Common Era year minus 1911 equals ROC year.

Day Counters, Ranges, And Deadlines

從…到… marks a span; 截止/截止日 marks the deadline; 以前/之後 add “before/after.”

活動從2025年6月1日到6月30日。
huó dòng cóng èr líng èr wǔ nián liù yuè yī rì dào liù yuè sān shí rì
The event runs from June 1 to June 30, 2025.

報名截止日:5月20日。

Saying “This Month,” “Next Month,” “Last Month”

Usage Notes & Common Mistakes

Don’t Swap Month/Day
Chinese goes big→small: 年→月→日, not “month day, year.”

「日」vs.「號」
「日」is formal/printed; 「號」is everyday speech. Both are correct for “day of month.”

Leading Zeros Are Style, Not Speech
You’ll see 06月、01日 in systems; in speech just say 「六月一號」.

Weekday Variants
星期 is the safe default. 週/禮拜 are fine in Taiwan; keep one style consistent inside a document.

ROC Year Pitfall
Remember CE − 1911 = ROC. For 2025, 民國114年. Don’t forget to convert on government forms.

Lunar vs. Solar
Unless you say 「農曆」, dates are assumed to be the solar (Gregorian) calendar.

Pronunciation Tips

年 nián:第二聲起伏輕;避免拖成平調。
月 yuè:第四聲乾淨下降,嘴形略圓。
日 rì:舌尖後捲,收尾短;在連讀中別變成「rih」。
號 hào:第四聲落得利落,和 好 hǎo 區分清楚。
星期 xīng qí:xīng 一聲平直;qí 第二聲上揚明顯。
民國 mín guó:兩個第二聲連續,上揚幅度別過大以免聽起來用力。

Practice Plan(Five Honest Minutes)

Read three full dates aloud, one formal, one spoken, one with weekday:
二〇二五年十二月一日;十二月一號;2025年12月1日(星期一)。
èr líng èr wǔ nián shí èr yuè yī rì; shí èr yuè yī hào; èr líng èr wǔ nián shí èr yuè yī rì (xīng qí yī)

Convert two CE years to ROC and back (write and say them).
把你的下個行程寫成日期+星期+時間三件組,然後念出來一次。
bǎ nǐ de xià ge xíng chéng xiě chéng rì qí + xīng qí + shí jiān sān jiàn zǔ, rán hòu niàn chū lái yí cì
Write your next appointment as date + weekday + time, then read it once.

Record a 15-second voice note scheduling a span with 從…到… and a deadline with 截止.
最後,用一句話說今天是幾號星期幾。
zuì hòu, yòng yí jù huà shuō jīn tiān shì jǐ hào xīng qí jǐ
Finally, say today’s date and weekday in one sentence.

Yak-Style Closing Spark

Chinese dates are Lego pieces: 年, 月, 日 snap together, 星期 clips on, and 民國年 is the special brick you pull out at government counters. Keep the big→small order, choose 日 or 號 to match the moment, and your calendar talk stays tidy, on-time, and drama-free.
