How to convert a Unix timestamp to a readable date
Turn Unix timestamps in seconds or milliseconds into local and ISO dates so logs, API payloads, and expiry fields are easier to debug.
Recommended tool
Open the matching ToolBento utility →Start by checking the timestamp length
Unix timestamps show up in logs, database rows, API responses, webhooks, analytics exports, and token claims. A ten-digit value is usually seconds. A thirteen-digit value is usually milliseconds. That difference matters because treating milliseconds as seconds can produce a date thousands of years away from the event you are trying to understand.
What to enter in ToolBento
Open ToolBento's Timestamp Converter and paste the value into the Unix timestamp field. The input can be seconds, such as 1780305164, or milliseconds, such as 1780305164000. Use only the timestamp number itself, not a full log line, JSON object, or surrounding label.
Press Convert for local and ISO dates
After the Unix timestamp field has the value you want to inspect, press Convert. The tool normalizes the input, then shows Unix seconds, Unix milliseconds, a Local date and time, and an ISO timestamp. That gives you a quick copyable result for bug reports, support notes, or comparing an API value with application logs.
Use ISO when you need an unambiguous time
The Local line is convenient when you want to understand the timestamp in your current browser timezone. The ISO line is better for sharing with teammates across regions because it is written in a standard UTC-style format. If a server log uses UTC and your coworker is in another timezone, the ISO value keeps the conversation cleaner.
Good debugging uses
Timestamp conversion is handy when checking cache expiry, webhook delivery times, scheduled job output, database created_at values, session lifetimes, analytics events, and JWT exp or iat claims. Convert the raw value first, then compare it with the system clock or log time around the failure you are investigating.
Common mistakes to avoid
Do not remove digits to make the date look right unless you know whether the source stored seconds or milliseconds. Also watch for timestamps stored as strings inside JSON, values rounded in spreadsheets, and time-zone assumptions in screenshots. If the result is wildly wrong, go back to the original source and confirm the full number was copied.
What the converter does not do
The Timestamp Converter reads one Unix timestamp value and formats it for inspection. It does not parse natural-language dates, batch-convert a whole file, or change the timestamp inside your database or API response. For code changes, use the converted result as evidence, then fix the source system separately.
