If you want a Jalali library for your application you are probably looking for
jelal.
This is a common library for Jalali and Gregorian date works at high levels for
cal- and date-like applications.
There are two binaries that you may be interested in as the final user:
jcalon https://crates.io/crates/jcal-caljdateon https://crates.io/crates/jcal-date
There is also another long abandoned project jcal (C based) and has no active
forks. These projects are not related in any ways. Moreover, all contributions
are welcome.
As defined in Cargo.toml.
