Oops, got the start date for the JDN incorrect. For some reason I thought it was -4799. Oh well, fixed now.

Quote:BTW, I see there is a compiler option INCLUDE_EASTER with code for calculating the easter date. Great! Why is this useful function missing in the current releases?

Walter was adamant that this function was not useful.

Quote:The code also shows that the LEAP? test accepts either an integer year in X or a date in the currently set format. I always thought that the former was required while the manual says the latter is needed ("Takes x as a date in the format selected, extracts the year, and tests for a leap year"). Actually LEAP? works in both cases. Walter?

Just a case of being more useful where possible.
