hcal - Hebrew date example programs for libhdate, a library that help use hebrew dates. LibHdate is a small C,C++ library for Hebrew dates, holidays, and reading sequence (parasha). It is using the source code from Amos Shapir's "hdate" package fixed and patched by Nadav Har'El. The Torah reading sequence is from tables by Zvi Har'El.
hcal [-hdi] [ [ month ] year ]
Hcal prints a calendar with both common and Hebrew dates for the specified month, or the whole year if no month is specified. If no arguments are given, it prints the current month. Major holidays are marked by a `*', other holidays by a `+', fast days by a `-'. If the year is greater than 3000, hcal takes the given date as a Hebrew date, and translates it back to the common calendar. Months are numbered with Tishrey being 1 and Elul 12; Adar I and Adar II are months 13 and 14. -h : Print output in html format. -d : Use diaspora reading and holidays. -i : Use external css file "./hcal.css".
