The collection of time-rs/time extensions for calendar arithmetics, incomplete formats handling, imprecise time, and other things time crate is not intended for.

• Introduces CalendarDuration and extends time::Date, time::PrimitiveDateTime and time::OffsetDateTime with several methods to enable arithmetic operations related to months and years. Additionally, attaches conversion methods to i64 and f64 to improve ease of use.

use time::{Date, Month::*};
use timext::ext::NumericCalendarDuration;

fn main() {
    let d0 = Date::from_calendar_date(2023, January, 31);
    let d1 = Date::from_calendar_date(2023, February, 28);
    assert_eq!(d0.unwrap() + 1.months(), d1.unwrap());

    let d0 = Date::from_calendar_date(2024, February, 29);
    let d1 = Date::from_calendar_date(2025, February, 28);
    assert_eq!(d0.unwrap() + 1.years(), d1.unwrap());
}

• Implements its own time::Time, time::Date, time::PrimitiveDateTime, and time::OffsetDateTime types, that are convertable from/to original, but allow incomplete time formats e.g. xx:24:xx.845, 1998-xx-02 or 2016-08 14:xx.

Warning : parsing & formatting are not yet implemented.

use time::{Date, Month::*};
use timext::{InComplete, InDate};

fn main() {
    let d0 = Date::from_calendar_date(2023, January, 28);
    let d1 = InDate::from_calendar_date(None, None, Some(28));
    let d1 = d1.unwrap();

    let d1 = d1.replace_year(Some(2023)).unwrap();
    let d1 = d1.replace_month(Some(January)).unwrap();
    assert_eq!(d0.unwrap(), d1.into_complete().unwrap());
}
