[amsat-bb] Pass Past/Future

[Pedro Converso]

Hi Roy,

THANKS! for nice & rewarding comment on new calendar facility on
http://amsat.org.ar/pass

The past & future passes where a date can be selected are calculated
on the fly using as you wisely said from current keps. However if a
much further/previous date (over three months) is selected calculation
will have a minor difference with actual, given keps changes over
time.

Have a good time and enjoy the birds.

73, lu7abf, Pedro
