julianday 1.2.0

Julian day is the continuous count of days since the beginning of the Julian Period. This crate implements a method to convert a JulianDay to and from the chrono's NaiveDate.

Julian Day (JD)

use chrono::NaiveDate;
use julianday::JulianDay;

fn main() {
    let naivedate = NaiveDate::from_ymd(2020, 2, 18);
    let julianday = JulianDay::from(naivedate);
    let date = julianday.to_date();
}

Modified Julian Day (MJD)

use chrono::NaiveDate;
use julianday::ModifiedJulianDay;

fn main() {
    let naivedate = NaiveDate::from_ymd(2020, 2, 18);
    let mjd = ModifiedJulianDay::from(naivedate);
    let date = mjd.to_date();
}
