HAPPY DAYS (1K ZX-81)
by Hsieh Min Hon
from Sinclair User 34 (January 1985), page 102

The quaintly-named Happydays is a calendar program which will tell you the day
of the week for any given date, as long as it falls after the introduction of
the Julian calendar. That will almost certainly include all of our reader's
brithdays, so the program is a good opportunity to discover if you are merry
and gay, or work hard for a living, according to the old rhyme.

Enter the day and month as figures, and the year in full, e.g. 1985. Happydays
was written by Hsieh Min Hon of Singapore and runs on the ZX-81 in 1K.
