Epoch Calculator is a remote MCP server that gives an AI agent 8 tools, among them convert_timestamp, convert_timezone, cron_next_runs. It answers at https://epochcalc.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 8 of 8 times since 6 September 2026; the last check, on 17 October 2026, succeeded.
Unix timestamps, DST-aware time zone conversion, durations, cron schedules, and holiday countdowns
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
convert_timestamp | Convert a Unix timestamp (seconds or milliseconds; auto-detected unless unit is given) to a human-readable date in a time zone, with ISO 8601, RFC 2822, UTC offset, DST flag, weekday, and a relative phrase like "3 days ago". Inputs: timestamp, unit, timezone |
convert_timezone | Convert a wall-clock date/time from one IANA time zone to another, correctly across daylight-saving transitions. Returns both sides with offsets, the hour difference at that instant, and whether either zone is on DST. Inputs: datetime, from_timezone, to_timezone |
cron_next_runs | Explain a 5- or 6-field cron expression in plain English and list its next run times in a time zone (as ISO 8601 and Unix timestamps). Use to answer "when does this cron job run next?" or to validate an expression. Inputs: expression, timezone, count, from |
date_duration | The exact duration between two dates or date-times: calendar years/months/days, plus total days, hours, minutes and seconds, and the number of weekdays (Mon-Fri). Handles leap years and DST via the IANA database. Inputs: start, end, timezone, include_end |
days_until | Countdown to a holiday or to a date: days, hours and minutes remaining, and the next occurrence date. Pass an event slug (e.g. "christmas", "thanksgiving", "easter", "super-bowl") or a date (YYYY-MM-DD). Call with no arguments to list the k Inputs: event, date, timezone |
epoch_math | Add to or subtract from a Unix timestamp in calendar-aware units (years, months, weeks, days, hours, minutes, seconds) in a time zone, e.g. "now + 30 days" or "1748736543 - 3 months". Returns the resulting timestamp in every format. Inputs: timestamp, add, subtract, timezone |
parse_datetime | Parse a date/time string (ISO 8601, RFC 2822, HTTP date, SQL "YYYY-MM-DD HH:mm:ss", or a Unix timestamp) into a Unix timestamp and a normalized description. Strings without an offset are interpreted in the given time zone. Inputs: input, timezone |
time_now | The current time: Unix epoch in seconds and milliseconds, ISO 8601, and the local wall-clock time in a given IANA time zone with its current UTC offset and DST status. Use this before any relative date reasoning. Inputs: timezone |

It answered our last check on 17 October 2026 in 183 ms. Over 8 checks since 6 September 2026 it answered 8. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by epochcalc.com and served from epochcalc.com, the vendor's own domain: https://epochcalc.com/mcp.
8, as returned by the server's own tools/list on 6 September 2026: convert_timestamp, convert_timezone, cron_next_runs, date_duration, days_until, epoch_math, parse_datetime, time_now.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://epochcalc.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: com.epochcalc. Endpoint host: epochcalc.com. ARD identifier: urn:air:com.epochcalc:mcp:epochcalc.
First indexed 6 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
