Horology Event: It’s a Leap Year!

February 7th, 2012 | No Comments

February is full of holidays – President’s Day, the Super Bowl, Valentines Day…the list goes on. And every few years another holiday is added…Leap year. Nearly every four years in the Gregorian calendar is a leap year. Julius Caesar first introduced the Leap year in the Roman Empire, but it has since been modified. Leap years are needed to keep our calendar in alignment with the Earth’s revolutions around the sun. It takes the Earth 365.242199 days to circle the sun so if we didn’t add a day every few years our calendars would be way off.

So what does this mean for you wrist watch? Well, if you have a mechanical watch with an annual calendar you will have to adjust for the leap year manually. If you have a perpetual calendar feature no adjustment is necessary. Watches require upkeep to maintain their precision; this Leap year is no exception.
