Timestamp Converter
Convert timestamps between Unix epoch, ISO 8601, UTC, and human-readable formats. Parse and convert timestamps instantly with timezone support.
1768931902summarize The Bottom Line
This timestamp converter instantly translates between Unix timestamps (seconds and milliseconds since January 1, 1970 UTC), ISO 8601 standard format (YYYY-MM-DDTHH:mm:ss.sssZ), UTC time strings, local time representations, and human-readable date/time formats. Enter any timestamp format—Unix epoch numbers, ISO dates, or formatted date strings—and see automatic conversions to all major formats simultaneously. View current time live-updating in Unix seconds, Unix milliseconds, and local format for reference. Copy any output format with one click including Unix seconds, Unix milliseconds, ISO 8601, UTC string, local time, date only, time only, relative time ("2 hours ago"), and custom formats. Select from comprehensive timezone list organized by region to view timestamps in specific timezones worldwide, accounting for UTC offsets and Daylight Saving Time automatically. Perfect for debugging API timestamps, synchronizing databases across servers, converting log file timestamps, scheduling international events, troubleshooting timezone issues, parsing datetime strings from external systems, or understanding Unix epoch values in readable formats. Supports parsing multiple input formats automatically—paste Unix timestamps (with or without milliseconds), ISO 8601 strings, RFC 2822 dates, or standard date strings and the converter detects the format. All timestamp parsing and conversion happens locally in your browser using JavaScript Date API—no timestamps ever get transmitted to servers, ensuring complete privacy for sensitive time data from logs, databases, or internal systems.

Unix Timestamp
Unix timestamp is the number of seconds (or milliseconds) since January 1, 1970 00:00:00 UTC. It's a standard way to represent time in programming.
ISO 8601
ISO 8601 is an international standard for representing dates and times. Format: YYYY-MM-DDTHH:mm:ss.sssZ. The 'Z' indicates UTC timezone.
UTC Time
Coordinated Universal Time (UTC) is the primary time standard. It's not affected by daylight saving time and is used as a reference for all timezones.
Timezones
Timezones represent local time at different locations. They're offset from UTC by a specific number of hours and may adjust for daylight saving time.
Relative Time
Relative time shows how long ago (or in the future) a timestamp is compared to now. Examples: "2 hours ago", "in 3 days".
Client-Side Only
All timestamp conversions happen in your browser using JavaScript. No data is sent to any server.
check_circle Problems This Timestamp Converter Solves
- Eliminates Unix timestamp decoding confusion - Stop mentally trying to figure out if "1638360000" represents December 2021 or some other date. Instantly convert cryptic Unix epoch numbers to human-readable dates and times.
- Prevents timezone offset calculation errors - Forget manually adding or subtracting hours to convert UTC timestamps to local time. The converter automatically handles timezone offsets and Daylight Saving Time adjustments for accurate local times.
- Removes ISO 8601 parsing complexity - Avoid writing custom code to parse "2021-12-01T12:00:00.000Z" format strings. Paste ISO dates and see instant conversions to Unix timestamps, local times, and other formats.
- Saves time debugging API timestamp mismatches - Stop wondering why timestamps from external APIs don't match your expectations. Quickly convert their format to yours to identify discrepancies in seconds versus milliseconds, timezones, or date representations.
- Eliminates spreadsheet formula headaches - Forget complex Excel or Google Sheets formulas to convert Unix timestamps. Copy converted human-readable dates directly for use in reports, dashboards, or documentation.
- Prevents database timestamp sync issues - Avoid confusion when database timestamps use different formats than application code. Convert between formats to ensure consistent time representations across your stack.
- Streamlines log file timestamp analysis - Stop manually calculating when "1640995200" occurred in server logs. Convert log timestamps instantly to readable dates for troubleshooting errors, identifying patterns, or creating incident timelines.
- Removes relative time calculation complexity - Forget manually calculating "how long ago was this timestamp?" See automatic relative time displays like "2 hours ago" or "in 3 days" for quick temporal context.
- Eliminates format detection guesswork - Avoid wondering if an input is Unix seconds, milliseconds, or some date string format. The converter automatically detects and parses multiple timestamp formats without manual selection.
- Ensures complete privacy for sensitive timestamps - Stop using online converters that might log when you're analyzing timestamps from production databases, security logs, or confidential systems. All conversions happen locally in your browser without server transmission.
