Terminal Equivalent
Convert Unix timestamps directly in your terminal without any tools.
# Convert Unix timestamp to human-readable date (Linux/Mac) date -d @1733569200 # Output: Sat Dec 7 04:00:00 UTC 2024 # Mac/BSD syntax date -r 1733569200 # Get current Unix timestamp date +%s # Convert date to timestamp date -d "2024-12-07 04:00:00 UTC" +%s
Language Quick Reference
# Python import datetime ts = 1733569200 dt = datetime.datetime.fromtimestamp(ts, tz=datetime.timezone.utc) print(dt.isoformat()) # 2024-12-07T04:00:00+00:00 # Get current timestamp import time print(int(time.time()))
How It Works
Unix timestamps count seconds elapsed since the Unix epoch — January 1, 1970, 00:00:00 UTC. This date was chosen because it was a convenient round number when Unix was being developed at Bell Labs. Negative timestamps represent dates before 1970. The maximum 32-bit timestamp is 2,147,483,647 (January 19, 2038) — the Y2038 problem. 64-bit systems extend this to year 292 billion.
