This version of SickBeard uses both TVDB and TVRage to search and gather it's series data from allowing you to now have access to and download shows that you couldn't before because of being locked into only what TheTVDB had to offer. Also this edition is based off the code we used in our XEM editon so it does come with scene numbering support as well as all the other features our XEM edition has to offer. Please before using this with your existing database (sickbeard.db) please make a backup copy of it and delete any other database files such as cache.db and failed.db if present, we HIGHLY recommend starting out with no database files at all to make this a fresh start but the choice is at your own risk! Enjoy!

This method was ported from the work done by GM Arts,
|
|
on top of the algorithm by Claus Tondering, which was
|
|
based in part on the algorithm of Ouding (1940), as
|
|
quoted in "Explanatory Supplement to the Astronomical
|
|
Almanac", P. Kenneth Seidelmann, editor.
|
|
|
|
This algorithm implements three different easter
|
|
calculation methods:
|
|
|
|
1 - Original calculation in Julian calendar, valid in
|
|
dates after 326 AD
|
|
2 - Original method, with date converted to Gregorian
|
|
calendar, valid in years 1583 to 4099
|
|
3 - Revised method, in Gregorian calendar, valid in
|
|
years 1583 to 4099 as well
|
|
|
|
These methods are represented by the constants:
|
|
|
|
EASTER_JULIAN = 1
|
|
EASTER_ORTHODOX = 2
|
|
EASTER_WESTERN = 3
|
|
|
|
The default method is method 3.
|
|
|
