1816 (MDCCCXVI) was a leap year starting on Monday (dominical letter GF) of the Gregorian calendar and a leap year starting on Saturday (dominical letter BA) of the Julian calendar, the 1816th year of the Common Era (CE) and Anno Domini (AD) designations, the 816th year of the 2nd millennium, the 16th year of the 19th century, and the 7th year of the 1810s decade. Note that the Julian day for 1816 is 12 calendar days difference, which continued to be used from 1582 until the complete conversion of the Gregorian calendar was entirely done in 1929.
This year was known as the 'Year Without a Summer' because of low temperatures in the Northern Hemisphere, the result of the Mount Tambora volcanic eruption in Indonesia in 1815. The sulfur from this eruption reflected the sun's rays and caused global cooling.
