Epoch Timestamp Converter

The ultimate tool for converting between human-readable dates and Unix epoch timestamps.

Introduction

For database admins and software engineers debugging distributed system logs or synchronizing backend jobs, the need to instantly translate between readable calendar dates and precise Unix time is constant. This converter provides that essential bridge without requiring a CLI or external API call. Get real-time conversions between any standard date format and its Unix epoch representation in both seconds and milliseconds.

Unix epoch counts seconds since Jan 1 1970 UTC; 32-bit timestamps overflow on Jan 19, 2038 (the Y2038 limit).

How to Use

  1. Type or paste a standard date (like 2024-05-20T14:30:00Z) or a raw digit sequence into the input field.
  2. Watch the result area instantly populate with the corresponding epoch value in both seconds and milliseconds.
  3. Click either output block to copy the exact number to your clipboard for pasting directly into SQL queries or script variables.
  4. Swap to the opposite unit by toggling the directional arrow button between the two output fields.

FAQ

How do I convert a standard date like 'May 20, 2024' to epoch time?

Paste the full date string into the input field; the converter uses your browser's native ISO parser to calculate the exact Unix timestamp in seconds and milliseconds instantly.

Why do different converters show slightly different timestamps for the same date?

Locale settings and implicit timezone offsets cause drift; always pass explicit UTC designators (Z suffix or +00:00) to guarantee server-safe epoch consistency.

What is the technical difference between epoch seconds and epoch milliseconds?

Epoch seconds record integer seconds since the origin point, while millisecond variants multiply that base by 1000 to match JavaScript's Date.now() precision requirements.

Which adjacent developer tool handles the decoded values next?

Once you extract the timestamp, use our JWT Decoder to inspect token payloads and verify expiration claims, which are frequently stored as Unix epochs.
