Provides utility functions to manipulate chrono dates. Only NaiveDate is supported as of now. Support for naive and timezone aware DateTime coming soon.

The crate provides the following:

Transition APIs

Transition a chrono struct into a future or previous date using standardised methods like start_of_pred_iso8601_week() which provides the date on which the previous week starts. Such functions are provided for week, month and year.

Code Sample

use chrono::NaiveDate;
use chrono_utils::naive::DateTransitions;

let d = NaiveDate::from_ymd(2019, 3, 31);
assert_eq!(d.start_of_succ_year().unwrap(), NaiveDate::from_ymd(2020, 1, 1));

let d1 = NaiveDate::from_ymd(1996, 2, 23);
assert_eq!(d1.last_day_of_month(), 29);

let d2 = NaiveDate::from_ymd(1999, 10, 17);
assert_eq!(d2.start_of_pred_iso8601_week().unwrap(), NaiveDate::from_ymd(1999, 10, 4));
