Unix Timestamp ⇄ Date Time Converter
Convert Unix timestamps to human-readable date/time and the other way around. Perfect for debugging APIs, logs, and backend/frontend development. All conversions run in your browser, keeping sensitive data safe.
Choose which direction you want to convert timestamps.
Notes
- Unix seconds are commonly used in APIs and databases.
- Unix milliseconds are common in JavaScript
Date.now().

What is the Timestamp Converter from SONO-Solutions?
The Timestamp Converter from SONO-Solutions is a small developer utility for converting Unix timestamps to human-readable date/time — and back again. It's ideal for debugging APIs, inspecting logs, and keeping frontend/backend time calculations in sync.
When is a timestamp converter useful?
- • Reading server logs that only show Unix timestamps.
- • Inspecting API payloads that store time as integers.
- • Debugging differences between frontend and backend time.
- • Generating timestamps for queries, tests, or feature flags.
Features of the SONO-Solutions Timestamp Converter
- • Convert Unix timestamps ⟷ human-readable date/time.
- • Supports seconds and milliseconds (epoch seconds/ms).
- • Shows local time and UTC side by side (depending on client UI).
- • All conversions run locally in your browser — no data upload.
- • Completely free, no account, no subscription.
How to use the Timestamp Converter
- 1. Choose the direction: timestamp → date/time or date/time → timestamp.
- 2. For timestamp input, paste a Unix timestamp in seconds or milliseconds.
- 3. For date input, choose the date & time you want to convert.
- 4. Review the result in both local time and UTC if available.
- 5. Copy the value you need for your logs, tests, or API calls.
This makes it easier to reason about time-based data and avoid off-by-one-hour mistakes due to time zones or daylight saving changes.
Practical examples
- • Find the exact date/time of a production incident from a log timestamp.
- • Check whether an analytics event time aligns with a user session.
- • Generate a timestamp for a database query range filter.
- • Verify that frontend JavaScript date handling matches backend logic.
