  Description     : arithmetic for Gregorian, Hijri, Hebrew and other calendars

 libcalendars is a small C library with no dependencies beyond libc and
 libm, covering eight calendars behind one interface. It defines no data
 types of its own, so it can sit behind an existing date and time API
 rather than replacing one.
 .
 Compared to what is already in Debian:
 .
  * libicu covers Islamic, Hebrew and Persian calendars, but is a large
    C++ library with a substantial data payload and is awkward to call
    from plain C. It has no Babylonian, ancient Egyptian or Revised
    Julian calendar. Its Persian implementation uses the 33-year cycle,
    documented as valid from 1925 to roughly 2090 CE.
  * libitl handles Hijri conversion but none of the other calendars here.
  * jcal/libjalali covers the Solar Hijri calendar only; last upstream
    release [DATE].
 .
 For the Solar Hijri calendar, no arithmetic rule reproduces the official
 Iranian calendar exactly, since the official calendar is fixed by
 observation of the vernal equinox. The library uses the 2820-year cycle
 with a correction table for the years where that rule diverges from the
 published official calendar, and the test suite checks the result
 against a table of official leap years. The derivation of the table is
 documented in the source.
 .
 I am the upstream author of this library and use it in my own projects.
 There is no reverse dependency in Debian yet. I intend to maintain the
 package myself and need a sponsor; I will look for one via
 debian-mentors once the packaging is ready. Packaging will be hosted on
 salsa.debian.org, and I would welcome co-maintainers.
