I've packaged libhdate for VL 6.0. In addition to the library this package includes hcal, a CLI Hebrew/Jewish calendar app, and hdate, a command line tool to display the current date on the Jewish calendar.

libhdate: libhdate (C,C++ library for Hebrew calendar, dates, and holidays)
libhdate: LibHdate is a small C,C++ library for Hebrew/Jewish dates, holidays,
libhdate: and reading sequence (parasha). It uses source code from Amos Shapir's
libhdate: hdate package fixed and patched by Nadav Har'El. The Torah reading
libhdate: sequence is from tables by Zvi Har'El. Two command line utilities are
libhdate: included: hdate displays today's Hebrew date and hcal displays a
libhdate: Hebrew/Jewish calendar.
