    Yes, I am sure there is online almanac for download. For
    more than 1000 years, by the way.
    This was discussed on this list about 5-6 years ago.
    But my computer and hard disc crashed since then, and I lost the
    address. Frank knows where it is, I am 100% sure.
    It is an enormous file though so I did not download it then,
    using paper almanac or Frank's online almanac.
    
    Frank's online almanac uses this file if I remember correctly.
