Queen Elizabeth II becomes Britain’s oldest-ever monarch on Thursday, beating the record of Queen Victoria.

Queen Elizabeth will move past Queen Victoria to become Britain's oldest-ever monarch around noon today.

Victoria, born on May 24, 1819, lived for 81 years and 243 days.

Buckingham Palace, calculating longevity down to the hour, said Elizabeth would move past Victoria at about 5 p.m. Thursday — 12 p.m. ET.

The queen is also within eight years of breaking Victoria’s record for the longest reign. She would pass that milestone on Sept. 9, 2015.

The queen is now the fourth longest-reigning monarch. She would overtake King Henry III on March 5, and King George III in 2012.
