Day of week from Pocket Watch B

Archiver

Hi All,
I have a BS2, Pocket watch B and Parallax's voice module hooked up as a
talking clock. In addition to the time and date, I would like to say the name
of the day. Is there anyway to calculate the day of the week from the date
with just the BS2?

Given YY from 1 to 99 (for 2001 to 2099), MM as month from 1 to 12,
and DD from 0 to 31 (day of current month), the following formula
calculates the day of the week. Oh, YY, MM and DD have to be binary,
not BCD numbers.

dayofweek: 'Sunday=0,Monday=1, Tuesday=2,..,Saturday=6
DOW=MM-1*30+(MM/9+MM/2)-(MM max 3/3*(YY//4 max 1 +1))+
DD+(YY-1//100*365)+(YY//100/4)//7

See <http://www.emesystems.com/BS2math4.htm#JulianDate> for
explanation. The formula computes the ordinal number of days
starting with Jan 1 2001 as number 1, which was a Monday. Then it
divides modulo 7 to get the day of the week for any day in the
century.

Hmmm. I thought the pocket watch B had a day-of-week output, no?

>DD from 0 to 31 (day of current month)

Thanks guys.
All the links appear valid and I got some good info...and I copied Tracy's
formula into the code and it worked just fine...that little parallax speech
module is just talking his head off..including the day of the week now..

I didn't find anything in the pwb's docs that it returned the day of the
week....
