How to Use the Date & Time Formatter
The Date & Time Formatter is a developer and productivity tool that parses, converts, and formats date and timestamp values across multiple international standards. Whether you are building APIs, debugging server logs, writing database queries, or formatting user-facing timestamps, this tool generates exact, copyable strings in real time.
Step-by-Step Instructions:
- Enter Your Date or Timestamp: Type or paste any date string (such as ISO 8601
2026-08-25T04:15:00Z), a 10-digit Unix timestamp in seconds (1787610000), a 13-digit millisecond timestamp, or click ⚡ Current Time (Now). - Select Display Timezone: Choose between your local device timezone, UTC / GMT, New York (EST), London (GMT), Tokyo (JST), India (IST), or Sydney (AEST).
- Custom Pattern Generator: Build custom formatting tokens such as
YYYY-MM-DD HH:mm:ssorMMMM D, YYYY at hh:mm Awith live output rendering. - Copy Any Standard Output: Click the copy icon next to any format (ISO 8601, RFC 2822, Unix Epoch, SQL Datetime, US/EU formats, or Relative Time).

Frequently Asked Questions
What is the difference between Unix timestamp in seconds vs milliseconds?
A 10-digit Unix timestamp (e.g. 1787610000) counts elapsed seconds (used in Python, PHP, and Unix systems). A 13-digit timestamp (e.g. 1787610000000) counts elapsed milliseconds (used in JavaScript Date.now() and Java System.currentTimeMillis()).
How does timezone conversion work?
The tool uses the browser's native Internationalization API (Intl.DateTimeFormat) and the IANA Time Zone Database to calculate exact hour offsets and daylight saving time (DST) shifts.
