Question

How to convert only the date without time to a string in Rust

Answer 1

use chrono::{Local, NaiveDate};

// Convert a NaiveDate to a string (YYYY-MM-DD)
fn date_to_string(d: NaiveDate) -> String {
    d.format("%Y-%m-%d").to_string()
}

// Build a NaiveDate from integers
fn make_date(y: i32, m: u32, d: u32) -> NaiveDate {
    NaiveDate::from_ymd_opt(y, m, d).unwrap()
}

fn main() {
    // 1. Today's date
    let today = Local::now().date_naive();
    println!("Today's date is: {}", date_to_string(today));

    // 2. Hard-coded date
    let my_date = make_date(2025, 12, 7);
    println!("Hard-coded date is: {}", date_to_string(my_date));
}



/*
run:

Today's date is: 2026-05-30
Hard-coded date is: 2025-12-07
