Date Calculations

This is a crate supporting relative date calculations for Chrono's NaiveDate, most notably only Gregorian dates.

Usage

use chrono::prelude::*;
use date_calculations::*;

let twenty_twenty_one = NaiveDate::from_ymd_opt(2021, 1, 31).unwrap();

assert_eq!(next_year(&twenty_twenty_one).unwrap().year(), 2022);
assert_eq!(next_year(&twenty_twenty_one).unwrap().month(), 1);
assert_eq!(next_year(&twenty_twenty_one).unwrap().day(), 1);

assert_eq!(previous_quarter(&twenty_twenty_one).unwrap().year(), 2020);
assert_eq!(previous_quarter(&twenty_twenty_one).unwrap().month(), 10);
assert_eq!(previous_quarter(&twenty_twenty_one).unwrap().day(), 1);
