Easter Sunday computation

[oracle]

I haven't tried the routine, running Linux for my QB most of the time and all, and I simply don't have enough time (unless you would like me to host your routine on QBNZ...

My bad, my bad. I thought it ended on Palm Sunday, but I wasnt sure (i stopped giving up things when I was 10, yeah, i know i'm going to hell) so I checked this( http://www.kencollins.com/holy-04.htm ) website, which is apparently full of crap. But my mistake

Spanish carnival starts on Thursday before ash Wednesday, in Barcelona we call it Dijous Gras (greasy Thursday) it's the day schoolchildren celebrate their carnival, and it's a tradition to eat omelettes or sausages with egg added.
Tuesday before Ash Wednesday it's the Entierro de la Sardina, (Burial of the Sardine), a simbol of the end of the carnival and the start of the fast.

I have found a well documented page about Easter related feasts (you can start 60 days before and end 60 days after!!) It includes an applet calculating Easter date.

I checked out the site of ths Rev. Collins. He's got a few thinks messed up, so I wrote him an email.

My 20 year old son said to me recently "Be careful, the Internet is not a source of information".

Yes, you will find that the celebartion of carnival varies from place to place. Some move the date drastically so as to have their very own carnival which does not coincide with others.

I checked out the site you provided. It's very good altough some of the explanations are a bit verbose. The calculation of Easter and related dates looks good. I verified a few dates and they coincide.

Thanks again, Antoni.

I downloaded 3 algorithms from the mmontes site you provided. Then I ran them in parallel with my version inside the same program, comparing every Easter calculated between 1583 and 9999. These are the results:

MONTES version (which is taken from Mallen's table approach): Matched my results 100%, but only ran it up to 4099 'cause that's what the specs said.

BUTCHER version ( I think someone on the forum had this): Matched my results 100%.

OUDIN version: totally wrong results.

I hope this gives my version a vote of confidence.

Hey Mr Moneo... there is an 'edit' button up the top right of your post, ok? Triple posts are not cool

Toonski,
It turns out you were right, Lent begins on Ash Wednesday and goes for 40 days excluding Sundays. This makes the actual ending date a little nebulous, and there are many disagreements, but that's the way it is.
P.S. I also apologized to Rev. Collins.

However, for an arithmetic method of computing the date of Ash Wednesday, my previous formula still stands, which is:
a) The date of Palm Sunday minus 39 days, or
b) The date of Easter minus 46 days.

Sorry, but I dont know what the "edit" button is. Tell me when and how I should use it.

Yes I did 3 posts in a row. I was answering specific posts of other people. How should I do this in the future?
