Rust Chrono Relative Time Ago

A quick and dirty solution to get that "X days ago" String out of a chrono NaiveDateTime without any dependencies. Very easy to customize on-demand in your project!

use chrono::{NaiveDateTime, Utc};

pub fn time_ago(date: NaiveDateTime) -> String {
    let now = Utc::now().naive_utc();
    let duration = now.signed_duration_since(date);

    match duration.num_days() {
        0 => "today".to_string(),
        1 => "yesterday".to_string(),
        2..=6 => format!("{} days ago", duration.num_days()),
        7..=13 => "1 week ago".to_string(),
        14..=20 => "2 weeks ago".to_string(),
        21..=27 => "3 weeks ago".to_string(),
        28..=30 => "1 month ago".to_string(),
        31..=59 => format!("{} months ago", duration.num_days() / 30),
        60..=364 => format!("{} months ago", duration.num_days() / 30),
        365..=729 => "1 year ago".to_string(),
        _ => format!("{} years ago", duration.num_days() / 365),
    }
}
