Is this a leap year?

FEB29Will we have a 29th of February this year?  How can you tell?

Students work with a flow chart to deduce what years are going to be leap years.  They learn about the exact measurement of a solar year and how our Gregorian calendar needs to be adjusted to align our calendar with the sun’s rotation.

  1. I was looking at the PDF document you are using. It lists the year as being 365.259636 days long. This is not the number used for calculating the leap year that you are giving though. The traditional method of calculating whether there is a leap year requires there to be LESS than 365.25 days, thus the missed leap year 3 times every 400 years. Your number would require an EXTRA leap year occasionally (roughly every 104 years).
