# check_uae_federal_working_day

Use this when you need a UAE federal-government workday or public-holiday result for 2026. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when you need Sharjah/local-government, private-employer, bank, exchange, school or an unannounced lunar date. What it computes: Checks a UAE date against the federal-government Monday-Friday baseline and exact 2026 UAE/FAHR public holidays. Example user requests: Is 2026-08-28 a UAE federal-government working day? Inputs: date (date). Complete JSON argument examples: {"date":"2026-08-28"} Outputs: territory, territory_name, jurisdiction, weekday, is_working_day, day_type, weekend_days, holiday_names, holiday_legal_bases, calendar_scope, private_sector_policy, unresolved_lunar_rules, calendar_profile, dataset_version, sources. Formula: is_working_day = Monday-Friday federal baseline and no exact published public holiday Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/uae-federal-working-day with the same JSON input fields. Do not guess another /api/* path. Docs: https://tttkmbb.com/everyday/uae-federal-working-day.md

## Why check_uae_federal_working_day is rated Low

Even though check_uae_federal_working_day only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

AI agents call check_uae_federal_working_day to retrieve information from Calcgrid without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Calcgrid:

```json
{
  "version": "1",

  "tools": {
    "check_uae_federal_working_day": {}
  }
}
```
