Unix Timestamp Converter
Convert between Unix timestamps and human-readable dates instantly
Unix Timestamp Converter - Convert Epoch Time
Convert Unix timestamps to human-readable dates and vice versa. Supports milliseconds, microseconds, and multiple timezones.
A Unix Timestamp Converter translates between Unix timestamps and human-readable date and time formats. The Unix timestamp represents time as the number of seconds that have elapsed since January 1, 1970 at 00:00:00 Coordinated Universal Time, excluding leap seconds. This simple numeric representation is used universally in programming, databases, and system administration.
Converting between timestamps and dates is a frequent task in software development. Log files typically record events with Unix timestamps. Reading a log entry with a timestamp of 1718000000 requires conversion to understand when the event occurred. Database records often store dates as Unix timestamps for simplicity and timezone independence. When querying or debugging database data, converting timestamps to readable dates is essential.
The converter takes a numeric timestamp and displays the corresponding date and time in multiple formats and timezones. The date is shown in ISO 8601 format, RFC 2822 format, and locale-specific formats. Timezone conversions display the time in UTC, local time, and common timezones like Eastern Time, Pacific Time, and Central European Time.
Developers use the converter to generate timestamps for API testing. When testing endpoints that accept or return timestamps, having the ability to convert between formats ensures that test values are correct. An API that expects a timestamp parameter can be tested with a known value generated by the converter.
The converter also transforms dates back to Unix timestamps. Entering a date and time produces the corresponding timestamp value. This is useful when constructing database queries that filter by date ranges or when creating API requests that include timestamp parameters.
Subsecond precision is supported with millisecond and microsecond timestamps. Some systems store timestamps with fractional seconds, and the converter handles these formats correctly. A timestamp in milliseconds is divided by 1000 to get the seconds component while preserving the fractional part.
Relative time display shows how long ago a timestamp represents. A timestamp from five minutes ago shows five minutes ago. A timestamp from last year shows one year ago. This relative display makes it easy to understand the recency of events without calculating date differences.
Common timestamp values are shown as reference points including the current timestamp, the start of the current day in Unix time, the start of the current year, and well-known timestamps like the epoch start. These reference values provide context and serve as starting points for related calculations.

Timestamp Tips
- Most systems use seconds since epoch: Some APIs use milliseconds instead of seconds. Check the documentation to confirm which unit is expected.
- Store timestamps in UTC: Always store and transmit timestamps in UTC. Convert to local time only when displaying to users. UTC eliminates timezone confusion.
- Use timestamps for date arithmetic: Calculating differences between dates is straightforward with timestamps. Simple subtraction gives the exact number of seconds between two dates.
