The Chinese Date in Words tool turns a calendar date into full Simplified Chinese prose, following the standard 年月日 (year-month-day) order. Pick a date and get output like 二〇二六年六月六日 星期六, ready for letters, certificates, contracts and language practice.
How it works
Chinese formats a date in three distinct ways within the same string. The year is read digit-by-digit: each numeral becomes its character, so 2026 is 二〇二六 followed by 年. The month and day are read as ordinary cardinal numbers using 十 for tens — December is 十二月, the 25th is 二十五日, and the teens drop the leading 一 so the 15th is 十五日. Finally the tool derives the weekday from the date and writes it as 星期 plus a number, where Sunday is the special form 星期日 rather than 星期七.
The date you choose is validated so that impossible inputs (such as 30 February) are rejected rather than silently formatted.
The digit-by-digit year rule — and why it matters
The most common mistake in written Chinese dates is treating the year like an ordinary number. In Mandarin, years are always read digit by digit:
- 2024 → 二〇二四年 (not 两千零二十四年)
- 1949 → 一九四九年
- 2000 → 二〇〇〇年 (zero is written 〇, the circular zero character)
This contrasts with quantities, where 2,024 would be read as 两千零二十四. The distinction is consistent and learners who memorise it avoid a very visible error in formal correspondence.
Month and day number rules
Unlike the year, months and days use standard cardinal numbers:
- Months 1–9: 一月, 二月 … 九月 (January through September)
- Months 10–12: 十月, 十一月, 十二月
- Days 1–9: 一日, 二日 … 九日
- Days 10–19: 十日, 十一日 … 十九日 (the teens use leading 十, no initial 一)
- Days 20–29: 二十日, 二十一日 …
- Day 30–31: 三十日, 三十一日
The tool handles all these automatically, including the rule that drops the leading 一 in the tens place for days 10–19.
Weekdays in Mandarin
| Weekday | Mandarin |
|---|---|
| Monday | 星期一 |
| Tuesday | 星期二 |
| Wednesday | 星期三 |
| Thursday | 星期四 |
| Friday | 星期五 |
| Saturday | 星期六 |
| Sunday | 星期日 (not 星期七) |
Sunday is the exception: it uses 日 (day) rather than 七 (seven), though in casual speech 星期天 is also widely used.
Where to use this format
The 年月日 + 星期X format appears on official documents, school certificates, court filings, notarised letters and formal business correspondence. In contracts it is common to see the date written out in Chinese characters alongside or instead of numerals, partly for clarity and partly because characters are harder to alter than digits. The tool’s output is intended for exactly these contexts. The tool works with the Gregorian civil calendar only and does not convert to the traditional lunar calendar.
