The fact that 2100 will be the first skipped leap year since 1900 means that we will eventually have to think about the winner of the 2096 election and whether his/her presidency will last for 1460 days from 2097 to 2101, 2921 days from 2093 to 2101, or 2921 days from 2097 to 2105.
Also, January 20, 2097, will be a Sunday, so the future president will have a public inauguration ceremony on Monday, January 21, 2097.
Any ideas about the winner of the 2096 election? Dwight D. Eisenhower, Ronald Reagan, and Barack Obama all had their private ceremonies on Sunday, January 20 for their second term (in 1957, 1985, and 2013 respectively), so the trend may continue for the inaugurations of 2041, 2069, and 2097. If this trend continues throughout the 21st century, then the answer to the poll would be choice 2, "2921 days from 2093 to 2101".
