Question:
I would like some help in finding out about the golden number for predicting
or calculating the full moon and Easter. The Encyclopedia Britannica says
to find it by adding 1 to the calendar year (AD) and dividing it by 19, the
remainder being the golden number. If there is no remainder, the number is
19. Once the number has been calculated, how does one use it? What does
one do with it to arrive at the full moon date?

Replies:
I read the Britannica write up and it is not at all clear what you are sup-
posed to do. I got the following from an insert that came with my desk
calendar: Easter falls on the first Sunday following the arbitrary Paschal
Full Moon, which does not necessarily coincide with a real or astronomical
full Moon. The Paschal Full Moon is calculated by adding 1 to the remainder
obtained by dividing the year by 19 and applying the following table:

The date you get from the above table is this so-called Paschal Full Moon;
it may be a day or two off from the astronomical full Moon. So for 1994,
the "key" is 1; Apr 14 is a Friday, so Easter is Apr 16. The article does
not say what the range of years is to which this method applies; I would
hesitate to apply it except for years in the 19th, 20th, and 21 st centu-
ries.
