All the indications are that we will get an early ice-out this year. Possibly very early.

The earliest recorded ice-outs, since they started keeping records in 1887 (129 years ago), is day 82 of the year.

Depending on whether it is a Leap Year or not day 82 is either March 24 (non-Leap) or March 23 (Leap).

This year is a Leap Year. So 82 days into the year will be March 23.

Today, March 11, is day 70. So we have 12 days to play with.

There is a hope that ice-out this year might beat all records and fall on the Spring Equinox, which is on March 20.

Easter Sunday is on March 27. Given that Easter can fall between March 22 and April 25 ice-out on March 20 – 23 would mean that it was BEFORE the range of Easter.

Why It Is Called “Leap Day” & “Leap Year” — February 29, 2016.

The ‘Leap’, as in tomorrow’s February 29 “Leap Day“, refers to the fact that on Leap Years a given day LEAPS over one day of the week to break the nice, year-to-year sequence we have in Non-Leap Years.

So pick any date. I chose Christmas BUT any date works (other than Feb. 29 (of course). See the pattern in non-Leap Years. If Christmas fell on a Friday one year, and the next year was NOT a Leap Year, Christmas would fall on Saturday. That is true for all dates. BUT if it is a Leap Year, rather than falling on Saturday it will fall on Sunday (as will be the case this year). Christmas Date LEAPED over Saturday. Hence the ‘Leap’.

This concept of ‘Leap’ is not used in all cultures and languages. Some prefer the more technical intercalary year (year with ‘interposed’ or ‘inserted’ day) or a bissextile year (having to do with the old Roman practice known of “twice sixth”).

2016 ‘Leap Day’, February 29 Will Fall On A Monday — A Favorite Day For Leap Days.

I don’t know if you ever thought about it but calendars (through their very nature) repeat themselves — i.e., you have years where the dates fall on the same days of the week (which means that January 1 on both years fell on the same day of the week). As the above image shows the calendar for 2016 is the same as that for 1988. So if you had a 1988 calendar you could reuse it, sans any issues, this year. For 2017 you could reuse that of 1989.

Basically, typically within OUR lifetime, calendars repeat every 28 years BUT this is NOT always the case. That has to do with the ‘NO LEAP DAY on century years that are NOT divisible by 400’ caveat. [That meant that there were NO February 29s in 1900, 1800 or 1700 since those century years are not divisible (exactly) by 400. But there was a February 29 in 2000, because it was divisible. Same in 1600. 2100, 2200 & 2300 will NOT contain Leap Days. 2400 will. Bit confusing … right?]

Once the 400 year rule is factored in our Gregorian Calendar (after the pope) TOTALLY repeats itself, without exceptions to do with Leap Years, every 400 years. During these 400 year cycles there will always be 97 Leap Years and as such 97 Leap Days.

15 of those 97 Leap Days will fall on a Monday, as is the case this year and WAS in 1988, 1960, 1932 & 1904.

BUT if you go back 28 years from 1904, i.e., to 1876, February 29 was on a Tuesday. That was because 1900 was a Century Year (i.e., divisible by 100) BUT was not divisible by 400.

15 Leap Days will also fall on a Wednesday. But only 13 will fall on a Sunday, Tuesday or Thursday, and 14 on Friday or Saturday. Isn’t that cool?
