Description Brad Garcia 2000-03-24 20:38:49 UTC
Why shouldn't the cal program show years 10000 onward?

> cal 1 10000
cal: illegal year value: use 1-9999

Do you really care?

I cared enough to file a bug,
but I won't lose any sleep if it doesn't get fixed.

It just seems like a completely arbitrary limitation.  I can find no reason
for it.  The mathematics are the same past the year 9999.  The type-imposed
limit for year appears to be (((MAX_LONG - 379) * 400 / 146097) + 1),
or 5879610 for a 32-bit long.  This limitation occurs in the day_in_week()

I tried removing the artificial limitation and it appears to give
correct results.
