The '''year 2011 problem''' or the '''Y1C problem''' ({{zh|t=民國百年蟲 |s=民国百年虫 |p=Mínguó bǎinián chóng |l=Minguo Year 100 bug}}) was a potential problem involving [[computers]] and [[computer systems]] in [[Taiwan]] in the night of 31 December 2010 and 1 January 2011.<br />
<br />
Similar to the [[year 2000 problem]] faced by much of the world in the lead-up to 2000, the year 2011 problem is a side effect of Taiwan's use of the [[Republic of China calendar]] for official purposes. This calendar is based on the founding of the [[Republic of China (1912–1949)|Republic of China]] in 1912 (year 1), so the year 2011 on the [[Gregorian calendar]] corresponds to year 100 on Taiwan's official calendar, which posed potential problems for any program that only treats years as two-digit values.<ref>[http://y100.dgbas.gov.tw/y100/faq/faq.asp Y1C problem FAQ] {{webarchive |url=https://web.archive.org/web/20100313141209/http://y100.dgbas.gov.tw/y100/faq/faq.asp |date=March 13, 2010 }}, Minguo Year 100 Problem Service Web (Traditional Chinese), Retrieve at 2010-04-27</ref><br />

==Reported problems==<br />
As most Taiwanese had anticipated the problem after the [[year 2000 problem]], the Y1C computer bug impact was minimal. Many computers were already using a three-digit system for dates, with a zero being used as the first digit for years below 100 (Gregorian 2010 or earlier).{{citation needed|date=July 2022}}<br />
<br />
Some government documents such as driver's licenses already refer to years over 100; nothing more than minor glitches were reported.{{citation needed|date=December 2014}}<br />
<br />
Some [[iPhone]] users reported that their alarm tool failed to function on 1 January 2011.<ref>{{Cite web|last=自由時報電子報|date=2011-01-02|title=百年蟲作怪 100年變00年 - 生活|url=https://news.ltn.com.tw/news/life/paper/456759|access-date=2020-12-18|website=自由時報電子報|language=zh-Hant-TW}}</ref>{{clarification needed|date=December 2014}}<br />
