chrono

Date and time library for Rust.

What it is

chrono provides date, time, timezone-aware datetime types, duration arithmetic, and parsing and formatting. Core types include NaiveDate and NaiveDateTime for calendar arithmetic without timezone, and DateTime<Tz> for timezone-aware values. Timezone support is extended by the chrono-tz companion crate.

Why it is commonly used

The standard date and time library in Rust. Used for timestamp handling in databases, APIs, log parsing, scheduling, file metadata, and any code that works with human calendar time.
