What is Mondayization?

Mondayization occurs when a public holiday falls on a day that is not a normal working day for an employee, such as a Sunday. In such cases, the tool identifies eligibility for a substitute holiday on the following Monday.

How do I check my total paid holidays for the year?

You can use the `calculate_annual_holiday_summary` tool by providing the target year and your work schedule to get a full count of paid holidays and Mondayization events.

Which AI clients can use this tool?

This tool is compatible with Cursor, VS Code, Claude Desktop, Windsurf, and any other MCP-compatible client via Vinkius Edge.

This MCP server provides deterministic calculations for Singapore public holidays based on the Employment Act. It determines if a holiday triggers 'Mondayization' (a substitute holiday) if it falls on a non-working day like Sunday. Use get_holiday_details to check specific dates, get_work_schedule_info to validate employee schedules, or calculate_annual_holiday_summary for a yearly overview of paid holidays and substitute events.
