San Marino operates on Central European Time (CET) during winter months, which is 1 hour ahead of Coordinated Universal Time (UTC+1). During daylight saving time, observed from the last Sunday in March to the last Sunday in October, San Marino switches to Central European Summer Time (CEST), which is UTC+2.
All of San Marino follows the same timezone. The microstate is entirely surrounded by Italy and shares its timezone with its larger neighbor. San Marino is one of the world's smallest and oldest republics.
San Marino claims to be the world's oldest surviving republic, founded in 301 AD. Despite being only 61 square kilometers, it has its own football team, Olympic committee, and postage stamps that are prized by collectors. The country is governed by two Captains Regent who serve together for just six months at a time.
