Date to Unix Timestamp Converter

Date to timestamp in code

// JavaScript — ISO string with offset
Math.floor(Date.parse('2026-09-19T12:30:00Z') / 1000);   // seconds

// JavaScript — a specific timezone without Temporal
new Intl.DateTimeFormat('en-US', { timeZone: 'America/New_York' });

// Python
from datetime import datetime, timezone
int(datetime(2026, 9, 19, 12, 30, tzinfo=timezone.utc).timestamp());

// PHP
strtotime('2026-09-19 12:30:00 UTC');

// PostgreSQL
EXTRACT(EPOCH FROM TIMESTAMP '2026-09-19 12:30:00+00')::bigint;

Common mistakes

• Assuming the server's timezone. new Date("2026-09-19 12:30")parses in the runtime's local zone, while new Date("2026-09-19")parses as UTC midnight. Two nearly identical strings, two different instants.
• Forgetting seconds vs milliseconds. JavaScript's Date.parse()returns milliseconds; divide by 1,000 before storing a seconds-based timestamp.
• Hardcoding UTC offsets. Offsets change with DST. Use IANA zone names like Europe/Berlin, not +02:00, and let the timezone database resolve the offset for the specific instant.

Free-form date input

Prefer typing the date yourself? The universal converter below accepts ISO 8601, RFC 2822 (Sat, 19 Sep 2026 12:30:00 GMT), plain2026-09-19 12:30:00 and bare timestamps. Date-times without an offset are interpreted in the timezone you select.
