Private by design
This conversion runs entirely in your browser. Your text is not sent to a server.
Tip
Values under 1e12 are treated as Unix seconds. Larger numbers are milliseconds.
How to inspect with Timestamp Converter
Paste a URL, Unix timestamp, date, or 5-field cron expression.
The parsed parts update as you type — nothing is uploaded.
Use Analyze to open URL Parser, Timestamp Converter, or Cron Explainer.
Copy the parts you need. Invalid input shows an error instead of a result.
When should you use it?
URLs
Split a link into host, path, query, and hash without a debugger.
Time
Convert Unix seconds to ISO UTC, or a date string back to Unix.
Cron
Read a 5-field expression before you paste it into a scheduler.
Stays here
Links, timestamps, and expressions never leave this tab.
Your values stay private.
URL parsing, timestamp conversion, and cron explanations run entirely in your browser.
About converting Unix timestamps locally
Timestamp Converter turns Unix seconds or milliseconds, or an ISO-8601 string, into Unix seconds, milliseconds, ISO UTC, and a local calendar reading. Values under 1e12 are treated as seconds; larger values as milliseconds — a common convention that still surprises people who paste 13-digit seconds by mistake. The result updates as you type. There is no Run button. Input is not persisted so a log line with a customer id does not stick around.
This is not a timezone database UI. Time Zone Converter is the sibling when the question is “what wall clock is it in Tokyo?” here the question is “what instant is this integer?” Leap seconds are not applied as a separate table. Invalid strings show an error. All math stays in the tab.

Date Calculator
Add or subtract days, weeks, months, or years from a start date. Months follow the civil calendar, including short-month overflow. Results update as you type.
Days Between Dates
Count signed calendar days between two dates using UTC midnights, plus an inclusive count of both endpoints. Weekends still count — use Working Days for weekdays only.
Time Zone Converter
Convert a wall-clock date and time between IANA time zones, including DST on that calendar date. Search zones such as Asia/Ho_Chi_Minh. Nothing is uploaded.
Cron Explainer
Translate a 5-field cron expression into plain English. The explanation updates as you type.
