02/29/2016 – Ephemeris – Yea! It’s the Leap Day.

February 29, 2016

Ephemeris for Monday, February 29th.  The Sun will rise at 7:21.  It’ll be up for 11 hours and 8 minutes, setting at 6:29.   The Moon, 1 day before last quarter, will rise at 1:19 tomorrow morning.

Today is one of those special days that only occur once every 4 years.  It’s the intercalary or leap day that compensates for that fact that the earth takes 365 and nearly a quarter day to orbit the sun.  That orbit is a year, and those quarter days are accumulated and added as the last day of February on years divisible by 4.  The Gregorian reform makes a slight adjustment on most century years, making century years not divisible by 400 ordinary years to keep the calendar in sync with the seasons.  The Romans, from who we’ve gotten our calendar considered the month of February as unlucky, and so shortened it.  Enjoy your extra day today, too bad it’s a Monday.  My bobmoler.wordpress.com blog post from yesterday explains it in more detail.

Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
