Did You Know? Taiwan’s Official Calendar Says It’s Year 115 (Not 2026)

Book a hotel in Taipei and the confirmation email says arrival: 115/08/28. Buy a bubble tea and the receipt is stamped 民國115年. Renew a Taiwanese friend’s driver’s license and the expiry reads 119年. If you’ve spent time in Taiwan, you’ve been quietly time-traveling — and here’s the story behind the numbers.

Taiwan Is Officially 115 Years Old

Not the island, of course — the island is millions of years old. But the Republic of China — the political entity that has governed Taiwan since 1945 — was founded on January 1, 1912, the day Dr. Sun Yat-sen was inaugurated as its first provisional president after the fall of the Qing Dynasty. That year became Minguo 1 (民國元年). Every year since counts up.

Quick math: Gregorian year − 1911 = Minguo year. So 2026 is Minguo 115. Simple.

What throws visitors is not the math — it’s the ubiquity. The 民國 (Mínguó, “Republic”) calendar isn’t a museum relic. It’s the official dating system for every government document in Taiwan, and it lives on top of the Gregorian 西元 (Xīyuán, “Western era”) calendar in daily life, not underneath it.

Where You’ll See Year 115 in the Wild

• Taiwanese national ID cards — date of birth in Minguo.
• Driver’s licenses — issue and expiry dates in Minguo. That expiry of “民國125年” is 2036, not the year 125.
• Bank statements & receipts — the date stamp at a 7-Eleven checkout is often Minguo.
• Government forms & tax filings — always Minguo. If a form asks for your birth year and you’re not Taiwanese, write your Gregorian year and let the clerk convert it.
• Legal contracts — signing dates get spelled out: “中華民國一百一十五年八月二十八日” (Republic of China, Year 115, August 28).
• Passports — issue date is printed with both calendars, so foreigners can read it.

Even train tickets, museum admission slips, and hospital appointment cards default to Minguo. Locals switch between the two calendars mid-sentence without a blink: “I moved to Taipei in 1998” and “my lease is up in 民國116年” can appear in the same conversation.

Why It Stuck

When the Kuomintang government retreated to Taiwan in 1949 after losing the Chinese Civil War, they brought the ROC calendar with them. Mainland China switched to the Gregorian system in 1949; Taiwan kept Minguo as a matter of continuity — a bureaucratic thread stretching back to the founding of the Republic. Seven decades later, no one is in a hurry to change it, especially the government offices whose entire records are Minguo-dated.

The Traveler’s Cheat Code

If a form, receipt, or ticket shows a three-digit year (105, 110, 115), just add 1911. If it shows a four-digit year (2026), leave it alone. And if someone asks for your birth year in Minguo, subtract 1911 from your Gregorian birth year — a friend born in 1990 was born in 民國79年.

Next time you scroll through Taiwan’s digital arrival card portal and see dates flipping between formats, or catch 民國115年 stamped on your MRT day pass receipt, you’ll know what you’re looking at. It’s not a typo, and you haven’t slipped 1,911 years into the past. You’re just reading the world’s most cheerfully bilingual calendar system.

Fun bonus: the Taiwanese lunar-solar farmer’s calendar (農民曆) still runs alongside both — meaning traditional families keep track of three calendars at once. It’s a small miracle nobody ever misses a birthday.
