Easter 2011

With our crazy hectic schedule, we decided to dye Easter eggs a week early this year. Our favorite Miss Kimberlee was in town watching her nephews while her sister was traveling, so we had her and Logan over to join us. I like having a lot of cups, it always gets the job done faster!

I wanted to get a picture of the kids with the Easter Bunny, but Natalie was not having it! Every time we got within touching distance, she would scream bloody-murder....definitely not worth it....She did like the bunny ears however.
The Easter Bunny came on Saturday to our house. He had forgotten how many things he had been accumulating in his warehouse, and both of the kids were totally full! Always fun.
We got to do a few different Easter Egg hunts this year. The high school music honor society put on an Easter Egg hunt at the high school, so we got to go there on Saturday afternoon. Carson got several eggs, Natalie got one, it's hard to compete with big kids.
On Sunday morning before church we went out to Garry's cousin's house for brunch, and the did a small hunt for the kids. We dumped them out for Natalie so she could extend the fun.
After church, we went to Garry's Aunt Sue's house for dinner, and Egg hunt #3. It was super fun for them to finally be able to fill up their baskets. Natalie figured out very quickly that if you pop them open, that's where the goods are, so we quickly got rid of all the candy.
I was so excited for Easter to be later this year, I thought for sure spring would have arrived, and we would be set. We got lucky with the nicest weather both Saturday and Sunday that we had had in weeks, now if it would only fling into spring.

I was really curious this year why there has been such a span of time in when Easter was. I always it had to do with some ancient Roman-Catholic thing, but our home teacher found this article that was pretty interesting, it isn't totally religious, but interesting none-the-less.

Easter is an annual festival observed throughout the Christian world. The date for Easter shifts every year within the Gregorian Calendar. The Gregorian Calendar is the standard international calendar for civil use. In addition, it regulates the ceremonial cycle of the Roman Catholic and Protestant churches. The current Gregorian ecclesiastical rules that determine the date of Easter trace back to 325 CE at the First Council of Nicaea convened by the Roman Emperor Constantine. At that time the Roman world used the Julian Calendar (put in place by Julius Caesar).

The Council decided to keep Easter on a Sunday, the same Sunday throughout the world. To fix incontrovertibly the date for Easter, and to make it determinable indefinitely in advance, the Council constructed special tables to compute the date. These tables were revised in the following few centuries resulting eventually in the tables constructed by the 6th century Abbot of Scythia, Dionysis Exiguus. Nonetheless, different means of calculations continued in use throughout the Christian world.

In 1582 Gregory XIII (Pope of the Roman Catholic Church) completed a reconstruction of the Julian calendar and produced new Easter tables. One major difference between the Julian and Gregorian Calendar is the "leap year rule". See our FAQ on Calendars for a description of the difference. Universal adoption of this Gregorian calendar occurred slowly. By the 1700's, though, most of western Europe had adopted the Gregorian Calendar. The Eastern Christian churches still determine the Easter dates using the older Julian Calendar method.

The usual statement, that Easter Day is the first Sunday after the full moon that occurs next after the vernal equinox, is not a precise statement of the actual ecclesiastical rules. The full moon involved is not the astronomical Full Moon but an ecclesiastical moon (determined from tables) that keeps, more or less, in step with the astronomical Moon.

The ecclesiastical rules are:

  • Easter falls on the first Sunday following the first ecclesiastical full moon that occurs on or after the day of the vernal equinox;
  • this particular ecclesiastical full moon is the 14th day of a tabular lunation (new moon); and
  • the vernal equinox is fixed as March 21.

resulting in that Easter can never occur before March 22 or later than April 25. The Gregorian dates for the ecclesiastical full moon come from the Gregorian tables. Therefore, the civil date of Easter depends upon which tables - Gregorian or pre-Gregorian - are used. The western (Roman Catholic and Protestant) Christian churches use the Gregorian tables; many eastern (Orthodox) Christian churches use the older tables based on the Julian Calendar.

In a congress held in 1923, the eastern churches adopted a modified Gregorian Calendar and decided to set the date of Easter according to the astronomical Full Moon for the meridian of Jerusalem. However, a variety of practices remain among the eastern churches.

There are three major differences between the ecclesiastical system and the astronomical system.

  • The times of the ecclesiastical full moons are not necessarily identical to the times of astronomical Full Moons. The ecclesiastical tables did not account for the full complexity of the lunar motion.
  • The vernal equinox has a precise astronomical definition determined by the actual apparent motion of the Sun as seen from the Earth. It is the precise time at which the apparent ecliptic longitude of the Sun is zero. (Yes, the Sun's ecliptic longitude, not its declination, is used for the astronomical definition.) This precise time shifts within the civil calendar very slightly from year to year. In the ecclesiastical system the vernal equinox does not shift; it is fixed at March 21 regardless of the actual motion of the Sun.
  • The date of Easter is a specific calendar date. Easter starts when that date starts for your local time zone. The vernal equinox occurs at a specific date and time all over the Earth at once.

Inevitably, then, the date of Easter occasionally differs from a date that depends on the astronomical Full Moon and vernal equinox. In some cases this difference may occur in some parts of the world and not in others because two dates separated by the International Date Line are always simultaneously in progress on the Earth.

For example, take the year 1962. In 1962, the astronomical Full Moon occurred on March 21, UT=7h 55m - about six hours after astronomical equinox. The ecclesiastical full moon (taken from the tables), however, occurred on March 20, before the fixed ecclesiastical equinox at March 21. In the astronomical case, the Full Moon followed its equinox; in the ecclesiastical case, it preceded its equinox. Following the rules, Easter, therefore, was not until the Sunday that followed the next ecclesiastical full moon (Wednesday, April 18) making Easter Sunday, April 22.

Similarly, in 1954 the first ecclesiastical full moon after March 21 fell on Saturday, April 17. Thus, Easter was Sunday, April 18. The astronomical equinox also occurred on March 21. The next astronomical Full Moon occurred on April 18 at UT=5h. So in some places in the world Easter was on the same Sunday as the astronomical Full Moon.

I LOVE the history of Easter here. We REALLY try to stress that with our kids. They don't really get squat for Easter. We still do egg hunts but that's about it.

i thought it was funny you said you liked having lots of cups cause it gets the job done faster.... remember when Carson and I had the job done in like 25 minutes that one year.... it was so funny!!!
