- Dear Nigel
-
- As I said in my last letter to you, I have been sent a BASIC program
- which calculates Easter Sunday from 1200 onwards. Brian Edwards has
- written to me giving me permission to send it to you.
-
- He has also sent me the algorithm for the calculation of Easter which
- he used in his BASIC program. I have converted that algorithm to a
- PipeDream 4 custom function which is in the file I have called
- [c_Easter2] on this disc. I have not thoroughly checked the custom
- function but all the years I have tried do match both your algorithm
- and the BASIC program sent to me by Brian.
-
- You will see that the algorithm used by Brian has built into it the
- year 1752 as the year for the change from Julian to Gregorian. I have
- written the custom function in such a way that this can be changed with
- relative ease.
-
- I shall be most grateful for any comment you have on the algorithm and
- any data you have of specific 'old' Easter dates which could be used to
- check the algorithm as well as its implementation by means of the
- custom function.
-
- Finally, I am looking forward to the the ecclesiastical calendar when
- you have done a little more work on it.
-
-
- Yours sincerely
-
