Function parseLocalDateTime

Parse an HTML datetime-local value into a local Date.

Accepted normalized values use a year with at least four digits followed by -MM-DDTHH:mm, with optional seconds and 1-3 fractional-second digits. Components are validated strictly, so impossible dates and times return null instead of being normalized by Date.

Usage:

import { parseLocalDateTime } from "mazey";

const date = parseLocalDateTime("2026-07-21T14:30:45.123");
console.log(date?.getFullYear());
console.log(date?.getHours());
console.log(date?.getMilliseconds());
Copy

Output:

2026
14
123
