Date Math Calculator is a Model Context Protocol (MCP) server: Date arithmetic: day differences, business days, age, leap years, day-of-week, add/subtract. Because it speaks the Model Context Protocol, AI assistants can use Date Math Calculator as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://apished.com/mcp/v1/datemath and you're connected, with nothing to install locally. The current release is v1.0.0.
On mcp.site, Date Math Calculator sits in the Development category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
