115/07/29 vs 115.7.29 vs 一一五年: Every ROC Date Format Explained

115/07/29, 115.7.29, 民國115年7月29日 and 1150729 are all the same date: 29 July 2026. Taiwan writes ROC dates in several formats depending on the document, but the underlying numbers never change.

Numeral formats with a separator

The most common format on printed cards and digital records uses a separator between year, month and day. The separator itself carries no meaning — it is purely a divider.

Slash	115/07/29  ·  also 115/7/29 without zero-padding
Dot	115.07.29  ·  common on forms and receipts
Hyphen	115-07-29  ·  common in spreadsheets and database exports
No separator	1150729  ·  seven digits: 115 + 07 + 29, used on barcodes and serials

All four represent 29 July 2026. Check the ROC year converter if you want the weekday or the formal written form for any of them.

The formal written form

Certificates, official letters and legal documents spell the date out in Chinese: 民國115年7月29日. 民國 (Minguo, "national era") marks the year as ROC-numbered, 年 means "year", 月 means "month" and 日 means "day". Drop 民國 and it still reads the same way: 115年7月29日.

You'll also see 中華民國 (the full name, "Republic of China") in place of 民國 on the most formal documents, such as certificates and court papers — the meaning and the numbers are identical.

Chinese numeral years

Some seals, certificates and older printed documents spell the year out using Chinese numerals read digit-by-digit rather than as a single number: 一一五年 is 1-1-5, i.e. 115, not "one hundred and fifteen" read as a magnitude word. This distinguishes it from how Chinese numerals are normally read (where 一一五 could look unusual) — in date contexts, each digit is read separately.

Digits	0 一 / 〇  ·  1 一  ·  2 二  ·  3 三  ·  4 四  ·  5 五
Example	一一五年 → 1,1,5 → 115 → 2026

Two-digit and unpadded years

Older documents, and some forms that predate today's four-character-wide year fields, write the ROC year without leading zeros: 85/3/2 is ROC 85 (1996), not 08 or 850. If a form has a fixed-width numeral field and the year is short, treat every digit before the month as part of the year rather than assuming a fixed length. For the specific problem this caused when the ROC year first reached three digits, see the Y1C problem.

Where each format shows up

Government IDs, permits and printed certificates favour the slash or formal written form; see the national ID card and the ARC. Bank and insurance paperwork often mixes slash and dot formats within the same form — see filling in ROC dates on bank forms. Packaged food and medicine tend to use the compact unseparated numeral form; see Taiwan food and medicine expiry dates.

Frequently asked questions

Are 115/07/29 and 115.7.29 the same date?

Yes. Both are ROC year 115, month 7, day 29 — 29 July 2026. Taiwan uses slashes, dots and hyphens interchangeably as separators; the meaning of the three numbers never changes.

What does 1150729 mean with no separators?

Read it as three chunks: 115 (year), 07 (month), 29 (day). This compact seven-digit form is common in printed serial numbers, barcodes and some database exports, and follows the same ROC-year-first order.

How do I read 民國115年7月29日?

民國 (Minguo) marks it as a ROC date, 115年 is the year, 7月 the month and 29日 the day — 29 July 2026. This is the full formal written form used on certificates and official letters.

What does a Chinese numeral year like 一一五年 mean?

Each character is read as a single digit, not as a magnitude: 一 (1), 一 (1), 五 (5) → 115. This spelled-out numeral form appears on formal certificates, seals and some older documents, and converts the same way as the numeral 115.

Do I ever need to convert the month or day in a ROC date?

No. Every ROC date format keeps the Gregorian month and day exactly as they are. Only the year element differs from a Western date, regardless of which separator or script is used.
