Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Zovo Date Calculator does exact date arithmetic: days between dates, business days (working days) excluding weekends and public holidays (including observed weekdays for holidays on a weekend) for 200+ countries and their states/regions, and the date N calendar or business days before or after a date. Pass dates as YYYY-MM-DD. Results are informational; legal deadlines may have special rules.

count_days_between — Count days between dates
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user asks how many days are between two dates (days between dates, count days, date calculator), how many business days or working days are between two dates, or days between dates excluding weekends and public holidays for a country or US state. Returns calendar days, weeks and days, years/months/days, business days, and the holidays skipped by name. The start date is counted; set include_end_date=true to also count the end date (Excel NETWORKDAYS style). Does not handle times of day or time zones. Holidays that fall on a weekend are not double-counted, and their observed weekday off (for example US Independence Day 2026 on Saturday is observed Friday July 3) is skipped as a holiday. Results are informational: legal deadlines may have special rules such as court holidays. Do not use for writing SQL or spreadsheet formulas.

calculate_date_offset — Find a date N days before or after
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants the date that is N days or N business days (working days) before or after a date: 'what date is 90 days from today', '30 business days from Nov 3, 2026 in Germany', '10 working days before 2027-01-15', shipping or contract deadlines. Business days skip weekends and the public holidays of the given country and state, including observed weekdays for holidays that fall on a weekend (US July 4, 2027 is a Sunday, so Monday July 5 is skipped); the start date is not counted. For calendar days, roll=next_business_day moves a result that lands on a weekend or holiday to the next business day. Returns the date with its weekday, the holidays skipped, and a calendar (.ics) file. Results are informational: court and filing deadlines may have special rules (court holidays, service days). Does not handle times of day.

list_holidays — List public holidays
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user asks which public holidays (bank holidays) a country or a state/region has in a year, e.g. 'Poland public holidays 2026' or 'Texas state holidays 2027', usually to plan working days. Returns each holiday with date, weekday, English name and whether it falls on a weekend, including the observed weekday off when a holiday falls on a weekend, plus a CSV file. Does not include school holidays, religious observances that are not days off, or company-specific closures. Do not use to check whether a stock exchange is open.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http zovo-date-calculator-mcp https://date-calculator.zovo.one/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add zovo-date-calculator-mcp --url https://date-calculator.zovo.one/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable zovo-date-calculator-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "zovo-date-calculator-mcp": {
      "url": "https://date-calculator.zovo.one/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "zovo-date-calculator-mcp": {
      "type": "streamableHttp",
      "url": "https://date-calculator.zovo.one/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start zovo-date-calculator-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "zovo-date-calculator-mcp": {
      "type": "http",
      "url": "https://date-calculator.zovo.one/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http zovo-date-calculator-mcp https://date-calculator.zovo.one/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "zovo-date-calculator-mcp": {
      "url": "https://date-calculator.zovo.one/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "zovo-date-calculator-mcp": {
      "serverUrl": "https://date-calculator.zovo.one/mcp"
