US Holiday Calendar?

Tue Feb 21 12:39:37 CST 2006

1.	Don't forget Lincoln's birthday.

2.	Labor Day is the first Monday after the first Tuesday in
September, I think.

3.	Don't forget Thanksgiving.

4.	Don't forget Christmas.

Thanks.

Subject: Re: US Holiday Calendar?

Hi, 

I was interested in the US holiday Calendar and therefore have collected
the following information. 

Holiday Calendar 

New Years   - 1st Jan 
Martin Luther King Jr.  - 3rd Monday of January 
Presidents Day  - 3rd Monday of the February 

Memorial Day - Last Monday in May 
Independence Day  - 4th July 
Labor Day  - Last Monday of May 
Columbus Day  - 2nd Monday of October 
Veterans Day  - November 11 
Good Friday  - 

I got the following from http://www.smart.net/~mmontes/nature1876.html 
The actual origin of this algorithm appears to be by an anonymous
correspondent from New York to Nature in 1876 (Thanks Denis!). Samuel
Butcher, Bishop of Meath, showed that this algorithm followed from
Delambre's analytical solutions, and produces the date of Easter for all
years. You can see the algorithm, as well as version for Orthodox Easter
at another Easter Date site. 
This algorithm appears in Practical Astronomy With Your Calculator, 2nd
Edition by Peter Duffett-Smith, and he obtained this algorithm from
Butcher's Ecclesiastical Calendar, published in 1876. This algorithm has
also been published in the 1922 book General Astronomy by Spencer Jones;
in The Journal of the British Astronomical Association (Vol.88, page 91,
December 1977); and in Astronomical Algorithms (1991) by Jean Meeus. 

This algorithm holds for any year in the Gregorian Calendar, which (of
course) means years including and after 1583. 

In the text below, / represents an integer division neglecting the
remainder, 
while % is division keeping only the remainder. So 30/7=4 , and 30%7=2 .

        a=year%19 
        b=year/100 
        c=year%100 
        d=b/4 
        e=b%4 
        f=(b+8)/25 
        g=(b-f+1)/3 
        h=(19*a+b-d-g+15)%30 
        i=c/4 
        k=c%4 
        l=(32+2*e+2*i-h-k)%7 
        m=(a+11*h+22*l)/451 
        Easter Month =(h+l-7*m+114)/31  [3=March, 4=April] 
        p=(h+l-7*m+114)%31 
        Easter Date=p+1     (date in Easter Month) 

I suppose from here, you can code your holidays for a year etc. 

Only thing I will say (Probably you already know) is that within HP
powerhouse, you get a day of the week by doing the
mod(day(sysdate),7), which would give you numbers from 0 to 6, where
zero is a Sunday. 

I hope this helps.

I search the archives but found nothing regarding generating a US
holiday calendar.  I found some algorithms on the net and unless someone
has already done it and is willing to share, I may build (and share)
procedures for a US holiday generator for a QUICK screen.
