| Tool | Description | Behaviour |
|---|---|---|
| add_working_days | Compute the date N working days after (or before, if N is negative) a start date for a UAE emirate/sector, skipping weekends and public holidays, and list every skipped day with its reason. Use for SLAs, delivery promises, HR processing times and 'within X business days' wording. Example: {start_date:'2026-05-21', days:3, emirate:'federal', sector:'public'} → end_date 2026-06-02 (Eid Al Adha week skipped). Response always includes data_confidence ('high' = all dates officially announced/confirmed, 'medium' = something is estimated), estimated_items[], sources[] (official URLs) and data_version. | Read-only |
| compute_deadline | Compute a deadline from a start date and a period in calendar days, working days, Gregorian months or Hijri months, applying the counting rules YOU specify (exclude start day, extend past weekends/holidays, half-day handling, estimated-holiday handling). Returns the deadline, the raw date before extension, every skipped day and a step-by-step explanation. Use when drafting contract, notice, appeal or payment deadlines in the UAE. This is date arithmetic only; it does not state what any law requires, and every response carries a disclaimer field. Example: {start_date:'2026-11-26', period:7, unit:'calendar_days', emirate:'federal', sector:'public'} → raw 2026-12-03 (National Day, estimated) → deadline 2026-12-04, data_confidence 'medium'. Response always includes data_confidence ('high' = all dates officially announced/confirmed, 'medium' = something is estimated), estimated_items[], sources[] (official URLs) and data_version. | Read-only |
| gregorian_to_hijri | Convert a Gregorian date to the Hijri (Islamic) calendar using the Umm al-Qura tables, with month names in English and Arabic. The result is COMPUTED: the official UAE date is set by moon sighting and may differ by ±1 day, so data_confidence is 'medium'. Use for Hijri-dated documents and to estimate Islamic holidays. Example: {date:'2026-03-20'} → 1 Shawwal 1447 AH. Response always includes data_confidence ('high' = all dates officially announced/confirmed, 'medium' = something is estimated), estimated_items[], sources[] (official URLs) and data_version. | Read-only |
| hijri_to_gregorian | Convert a Hijri date 'YYYY-MM-DD' (1343–1500 AH) to Gregorian using the Umm al-Qura tables, with the weekday. COMPUTED, ±1 day versus the moon-sighted UAE date; data_confidence 'medium'. Example: {hijri_date:'1448-01-01'} → 2026-06-16 (Tue). Response always includes data_confidence ('high' = all dates officially announced/confirmed, 'medium' = something is estimated), estimated_items[], sources[] (official URLs) and data_version. | Read-only |
| is_working_day | Tell whether a date is a working day in the UAE for a given emirate and sector, and why not (weekend, named public holiday with its status, or Friday half day). Call this before scheduling, promising delivery, booking, or filing anything on a UAE date. Islamic holidays depend on moon sighting: the result says whether the holiday is 'estimated' (not yet announced) or 'confirmed'. Example: {date:'2026-05-25', emirate:'federal', sector:'public'} → is_working_day=false, reason 'Eid Al Adha (extended federal break)', status confirmed; the same date for sector 'private' → true. Response always includes data_confidence ('high' = all dates officially announced/confirmed, 'medium' = something is estimated), estimated_items[], sources[] (official URLs) and data_version. | Read-only |
| list_holidays | List all public holidays for a Gregorian year, emirate and sector, with English and Arabic names, dates, status (estimated | announced | confirmed | moved, with original dates when moved), official source URL and last-checked time. Use for annual planning, HR calendars and to show users which dates are still provisional. Example: {year:2026, emirate:'federal', sector:'private'} → 8 holidays, National Day still 'estimated'. Response always includes data_confidence ('high' = all dates officially announced/confirmed, 'medium' = something is estimated), estimated_items[], sources[] (official URLs) and data_version. | Read-only |
| next_holiday | Return the next public holiday on or after a date for an emirate/sector: names (EN/AR), dates, status, days until, source. Use for 'when is the next long weekend / holiday' questions and to warn about upcoming closures. Example: {from_date:'2026-10-31', emirate:'federal', sector:'public'} → Eid Al Etihad 2–3 Dec 2026, estimated, 32 days away. Response always includes data_confidence ('high' = all dates officially announced/confirmed, 'medium' = something is estimated), estimated_items[], sources[] (official URLs) and data_version. | Read-only |
| ramadan_info | Return Ramadan start/end for a Gregorian year (observed or estimated) and the officially published reduced working-hour rules for the emirate/sector (e.g. federal 09:00–14:30 Mon–Thu, 09:00–12:00 Fri; private sector −2 hours/day). If no rule has been published for that profile the response says 'not_announced' instead of guessing. Use for scheduling during Ramadan and for HR policy questions. Example: {year:2026, emirate:'federal', sector:'public'} → 18 Feb–19 Mar 2026, confirmed, FAHR Circular 1/2026 hours. Response always includes data_confidence ('high' = all dates officially announced/confirmed, 'medium' = something is estimated), estimated_items[], sources[] (official URLs) and data_version. | Read-only |
| working_days_between | Count working days between two dates for a UAE emirate/sector (choose which endpoints to include), with the number of Friday half days and the list of non-working days in the range. Use for leave calculations, payroll, project durations and lateness. Example: {start_date:'2026-05-18', end_date:'2026-06-05', emirate:'federal', sector:'public'} → working_days 10, of_which_half_days 2. Response always includes data_confidence ('high' = all dates officially announced/confirmed, 'medium' = something is estimated), estimated_items[], sources[] (official URLs) and data_version. | Read-only |
| working_hours | Tell whether a specific datetime falls within standard working hours for an emirate/sector, taking into account weekends, holidays, the federal Friday half day (07:30–12:00) and official Ramadan hours. Private-sector hours are employer-specific; a default schedule is used and flagged. Use before calling a government office, scheduling a meeting or promising same-day action. Example: {datetime:'2026-03-05T13:00:00+04:00', emirate:'federal', sector:'public'} → within_working_hours true, hours_today 09:00–14:30 (Ramadan). Response always includes data_confidence ('high' = all dates officially announced/confirmed, 'medium' = something is estimated), estimated_items[], sources[] (official URLs) and data_version. | Read-only |
