The Canine Patient is a Cone Head on Leap Day at the Ranch

Bravo's cast is off...only to be replaced with a cone!! The vet tech said his bandage was the cleanest she's ever seen...so I did my job well putting it in a bag every time we went outside! Now he has to wear the cone for another week until the stitches are taken out. He hates the cone and I think he is a bit depressed about it. I take it off when he eats and during "special cuddle time" (yeah, he gets special cuddle time!)...if we survived a week with the ridiculous cast, we'll survive a week with conehead!!
Waiting at the vet...

The car ride there!

Downright embarrassing to wear in front of your canine siblings!
The donkeys finally get a long-awaited walk with Papa...and the hens.
Randy pretends to ride Paco.

My little canine patient.
All alone in the world as a conehead.

Sad, sad, sad.
Isabella has a thing about hanging out at the doors lately!

Boulder is worried because I haven't been paying much attention to him since Bravo's operation...so he brought me a mouse. I have to have the vegan talk with him again!
Paco in position to hee-haw.

Sophia lays her egg of the day!

The year 2008 is a leap year. If you look at a 2008 calendar, you will see that February has five Fridays–the month begins and ends on a Friday. Between the years 1904 and 2096, leap years that share the same day of week for each date repeat only every 28 years. The most recent year in which February comprised five Fridays was in 1980, and the next occurrence will be in 2036. February 29, the leap day, has been associated with age-old traditions, superstitions and folklore.
What is a leap year? A leap year is a year in which one extra day has been inserted, or intercalated, at the end of February. A leap year consists of 366 days, whereas other years, called common years, have 365 days.
Which years are leap years?
In the Gregorian calendar, the calendar used by most modern countries, the following three criteria determine which years will be leap years:
Every year that is divisible by four is a leap year;
of those years, if it can be divided by 100, it is NOT a leap year, unless
the year is divisible by 400. Then it is a leap year.
According to the above criteria, that means that years
1800, 1900, 2100, 2200, 2300 and 2500 are NOT leap years, while year 2000 and 2400 are leap years.
It is interesting to note that
2000 was somewhat special as it was the first instance when the third criterion was used in most parts of the world.
In the Julian calendar–introduced by Julius Caesar in 46 BC and patterned after the Roman calendar–there was only one rule: any year divisible by four would be a leap year. This calendar was used before the Gregorian calendar was adopted.
Why are leap years needed? Leap years are needed to keep our calendar in alignment with the earth's revolutions around the sun.

Note: The illustration above is not to scale.
The vernal equinox is the time when the sun is directly above the Earth's equator, moving from the southern to the northern hemisphere.
The mean time between two successive vernal equinoxes is called a tropical year–also known as a solar year–and is about 365.2422 days long.
Using a calendar with 365 days every year would result in a loss of 0.2422 days, or almost six hours per year. After 100 years, this calendar would be more than 24 days ahead of the season (tropical year), which is not desirable or accurate. It is desirable to align the calendar with the seasons and to make any difference as insignificant as possible.
By adding a leap year approximately every fourth year, the difference between the calendar and the seasons can be reduced significantly, and the calendar will align with the seasons much more accurately.
(The term "day" is used to mean "solar day"–which is the mean time between two transits of the sun across the meridian of the observer.)
