heca-lib is a blazingly fast Hebrew calender library. It's the backend behind the heca program.

use heca_lib::prelude::*;
use heca_lib::*;
This library can convert from Hebrew to Gregorian dates and back. You can get a HebrewDate either from a known Hebrew date or from a Gregorian date:
extern crate heca_lib;
use chrono::Utc;
use chrono::offset::TimeZone;
use heca_lib::prelude::*;
use heca_lib::HebrewDate;
assert_eq!(HebrewDate::from_gregorian(Utc.ymd(2018,9,10).and_hms(17,59,59)).unwrap(),HebrewDate::from_ymd(5779,HebrewMonth::Tishrei,1).unwrap());
You can then get back a Gregorian date from this Hebrew Date.
extern crate heca_lib;
use chrono::Utc;
use chrono::offset::TimeZone;
use heca_lib::{HebrewDate};
use heca_lib::prelude::*;
assert_eq!(HebrewDate::from_ymd(5779,HebrewMonth::Tishrei,10).unwrap().to_gregorian(),Utc.ymd(2018, 9,18).and_hms(18,00,00));
This library can also list the major Jewish holidays and Torah readings in a given year (for both Israel and the Diaspora):
extern crate heca_lib;
use heca_lib::{HebrewYear,HebrewDate};
use heca_lib::prelude::*;
assert_eq!(HebrewYear::new(5779).unwrap().get_holidays(Location::Chul, &[TorahReadingType::Shabbos])[0].name(), TorahReading::Shabbos(Parsha::Vayelach));
assert_eq!(HebrewYear::new(5779).unwrap().get_holidays(Location::Chul, &[TorahReadingType::SpecialParsha]).iter().find(|x| x.name() == TorahReading::SpecialParsha(SpecialParsha::Zachor)).unwrap().day(),HebrewDate::from_ymd(5779,HebrewMonth::Adar2,9).unwrap());
