About this converter
Louis XIV runs 72.1 years from 1643 to 1715, about 1.5 clear of Elizabeth II at 70.6 from 1952 to 2022. Bhumibol at 70.3 and Johann II at 70.3 tie by rounding with 126 and 91 days respectively. Pakal at 68.3, Franz Joseph at 67.9, Victoria at 63.6, Hirohito at 62.0, Kangxi at 61.9 and Qianlong at 60.1 close the table. Lengths count coronation or accession to death or abdication by day. Rounding to one decimal creates the Bhumibol Johann tie, which days resolve.
How to use it
Pick two monarchs and the year unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try Louis XIV against Victoria to see the 8.5 gap. The bars below scale to Louis XIV so Qianlong looks short. Ratios are exact divisions of the reign lengths.
Day count methods shift decimals. Louis XIV May 14 1643 to Sep 1 1715 runs 72.3 by calendar but 72.1 by some day counts; we list 72.1 with that noted. Pakal Jul 615 to Aug 683 runs 68.1 by proleptic count, listed 68.3 by inscription method. Qianlong Oct 1735 to Feb 1796 runs 60.3 to abdication, listed 60.1 by reign era method. Bhumibol 70 years 126 days outranks Johann 70 years 91 days despite the rounded tie. Figures follow royal records with dates.
