The Slavic Typikon is a massive book, containing hundreds of chapters. In it we find how to serve each of the services--how to serve daily Vespers and Matins, how to do them if there is a Feast Day, or how to do them during Great Lent. There are chapters that instruct us on how the choir is to sing together (and against "disorderly shrieks" that have no place in church singing). There are chapters that give clear instructions on how and when to cense, tables with Apostol, Gospel and Psalter readings. Then there is a very extensive calendar section, with an explanation of the services for every day of the fixed calendar year, and a separate section for how to do the services for all of the days that the Lenten Triodion and Pentecostarion are used.

The most amazing sections are those that explain how to correlate and combine the services of the fixed and moveable calendars. Every possible combination is considered. The rubrics for how to do the services of the Feast of the Annunciation, for example, are more than thirty pages long--they explain in detail how to put together the service for the Annunciation when it coincides with any possible day of Great Lent and Bright Week.

Looking at these detailed rubrics, one learns how to put together the service if Annunciation should coincide with the Saturday of the Akathist, Lazarus Saturday, Palm Sunday, or even Pascha itself. One learns how to serve a service to a saint having a "Polieleos" (such as St. George) if it should fall on Bright Week, etc.

The final sections of the Typikon are the Paschalion Calendar sections. Here, there are tables reflecting the 532 year cycle of the Church services (which consists of 19-year solar cycles multiplied by 28-day lunar cycles. There is a table that consists of 19 columns by 28 rows, giving the Paschal Key number (really a letter) for each of the years of the 532-year cycle. Once you know the Paschal Key, you look up the details in the following section, which consists of 35 brief calendar synopses (one for each possible day that Pascha can fall). Each of these synopses actually consists of two--one for regular years, and one for leap years.

For example, lets look at 1996.

The 532-year cycle is calculated from the creation of Adam, which, as we know, took place on Friday, March 1, 5508 B.C. (Yes, that is the base date on which the entire calendar system of the Orthodox Church is based--pretty neat, huh?)

So, you add 5508 to 1996 to get 7504, the year from the creation of Adam. Dividing this by 532, you get 14, with a remainder of 56. (This tells us that since the creation of Adam, we are only in the 15th cycle--not such a long time). Dividing 56 by 19, we get 2, with a remainder of 18. Looking at our Paschal Key table, in the third row in column 18, we find the Paschal Key of the Slavonic letter "I"--(which is the 11th Paschal Key). It is in red, which means the year is a leap year. Looking up the synopsis for the letter "I" we find the following:

"If it is a leap year: The Nativity of Christ is on a Sunday. The Post-Nativity meat-eating period is six weeks and a day. The Triodion begins on January 22. Meatfare Sunday is February 5. Cheesefare Sunday is February 12. The "Year Key" is 7. St. Eudokia is on Thursday of the third week of Lent. The 40 Martyrs are on Friday of the fourth week of Lent. St Alexis is on Saturday of the fifth week of Lent. Annunciation is on Palm Sunday. The Pascha of Christ is on April 1. St. George is on Monday of the fourth week after Pascha. Mid-Pentecost is on April 25. St. John the Theologian is on Tuesday of the sixth week after Pascha. Ascension is on May 10. Pentecost is on May 20. The Fast of the Apostles begins on the day after May 27. The Apostle's Fast is four weeks and four days long. St. Peter and Paul's is on a Friday."

And you can use these tables and synopses for any date you want--ever. If you should ask me, when Pascha should come in the year 2007, all I need to do is add 5508 (getting 7515), divide by 532, getting a remainder of 67. Dividing this by 19, I get 3, with a remainder of 10. Looking at the chart, I find in the fourth row and the 10th column the Paschal Key Letter of Slavonic "D"--which is the 5th Paschal Key. Turning to the Synopsis, I find that Pascha will fall on March 26, and all the other information about the congruence of feasts mentioned above.

When are Ascension and Annunciation in the year 35762? (I know that's pretty far into the future, but I want to show that it works for any year). 35762 + 5508 = 41270. Dividing by 532, we get a remainder of 306. Dividing that by 19, we get 16, with a remainder of 2. Looking at the table in the 17th row, second column, we find the Paschal Key letter "Zh"--which is the 7th Paschal Key. In the Synopsis, we find that Ascension that year will fall on May 6--Annunciation will fall on Holy Thursday.

The key point here is that the cycle is PERPETUAL. At the bottom of the table it says: "The Alphabetic Key for 532 years. And then it returns to its beginning, for this key will be applicable until the end of the ages."

In fact, the most important thing about the Typikon is that it is TIMELESS and PERPETUAL. It is good for this year, for a thousand years ago and for the future, FOREVER.

Well, here's the bad news. The geniuses that brought us the Calendar reform in 1923 TRASHED THE TYPIKON. It is no longer applicable to determine how the services are to be put together, and it is no longer perpetual.

Why? Because the Typikon takes into consideration only the possible combination of the fixed and moveable calendars that occurs with Pascha bound between March 22 and April 25. Therefore, Annunciation can only fall between Thursday of the 3rd week of Lent and Bright Wednesday. According to the "Revised Julian Calendar," right now Annunciation can fall between the Friday of the First Week of Great Lent and Thursday of the 6th week of Lent. Guess what? The Typikon has no rubrics on how to combine Annunciation with services of the First Week of Lent, or the Sunday of Orthodoxy. Such combinations are impossible under the traditional calendar used by the Typikon to combine services.

So, the wonderful masterpiece of the Holy Fathers' labors, the Typikon, is headed for the trash heap -- because it is useless under the New Calendar.
