Date & Time Tools

Convert Unix timestamps, parse ISO 8601 strings, convert between IANA time zones, calculate date differences and relative offsets, and parse or build cron schedules with next run times — essential for log debugging and scheduling.

Date & Time Tools

• Unix Timestamp Converter

  Convert between Unix timestamps (seconds or milliseconds) and readable dates. Paste a timestamp or date string, or leave empty for the current time.

• ISO 8601 Parser

  Paste an ISO 8601 date-time string to validate it and see a full breakdown across UTC, local time, and common time zones.

• Time Zone Converter

  Convert a date-time from one IANA time zone to another. Paste a timestamp or date string, select source and target zones, and click Run.

• Date Difference Calculator

  Find the duration between two dates. Enter start and end dates on separate lines or separated by |, then click Run.

• Relative Time Calculator

  Add or subtract a duration from a base date. Line 1: base date. Line 2: offset like +3 days, -2 weeks, or +90 minutes.

• Cron Expression Tool

  Parse an existing cron expression or build one field by field. Validate schedules, see human-readable descriptions, and preview the next run times in UTC.
