# Epoch Calculator Time and date math that language models get wrong on their own: Unix timestamps, daylight-saving offsets, calendar arithmetic, and cron schedules. Every calculation uses the IANA time zone database, the same engine behind [epochcalc.com](https://epochcalc.com). No API key, no signup, no state. Read-only. ## Tools | Tool | What it does | |---|---| | `time_now` | Current time in any zone, with epoch seconds, ISO 8601, RFC 2822, and DST flag | | `convert_timestamp` | Unix timestamp (seconds or milliseconds, auto-detected) to a full date breakdown | | `parse_datetime` | Natural or ISO date string to timestamp and zone-aware fields | | `convert_timezone` | Same instant in two zones, with the hour difference and DST status of each | | `date_duration` | Days, weekdays, weeks, and calendar breakdown between two dates | | `epoch_math` | Add or subtract years, months, weeks, days, hours, minutes, or seconds | | `cron_next_runs` | Plain-English explanation of a cron expression plus its next N run times | | `days_until` | Countdown to a named holiday or event, or list the supported events | ## Notes - Time zones are IANA names such as `America/New_York` or `Europe/Berlin`. Abbreviations like `EST` are ambiguous and rejected. - Endpoint: `https://epochcalc.com/mcp` (Streamable HTTP, stateless). A plain JSON API for the same tools is at `https://epochcalc.com/api/v1`. - Documentation: [epochcalc.com/api](https://epochcalc.com/api)
