I just uploaded Date::Passover, which lets you calculate the date of

Passover and Rosh Hashanah for any year between 1900 and 2099. That

restriction is just because I used the similified form of the formula.

I'll use the more complete form in the next version and remove that

restriction.

Also included in the distribution is Date::GoldenNumber. As you may

know, most of John Conway's date algorithms need that number as part

of the algorithm. Not that it's a concept unique to him, but just that

most of the algorithms I've been using lately are his algorithms. So I

expect that that module will not stay part of this distribution for

very much longer.
