United Arab Emirates reporting cycles and business-day rules

UAE business-day cycles align with FTA (Federal Tax Authority) VAT201 quarterly deadlines (28 days after quarter-end for non-grouped registrants) and monthly returns for designated taxpayers. The UAE Central Bank operates UAEFTS as the wholesale RTGS system on bank business days. The federal public sector switched from a Friday-Saturday weekend to Saturday-Sunday in January 2022 and the private sector largely aligned. Corporate income tax was introduced June 2023 at 9%; tax returns are due nine months after the financial year-end. Free Zone Persons under the Qualifying Free Zone regime enjoy 0% on Qualifying Income. ADGM and DIFC operate independent commercial-law regimes.

Frequently Asked Questions

How many business days are in December 2025 for UAE federal?
December 2025 has 20 working days under the UAE federal holiday calendar. The month spans 31 calendar days, of which 8 fall on a weekend and 3 are UAE federal holidays that lands on a weekday. The remaining 20 weekdays are countable as working days for invoicing, deadline tracking, and contract math.
Which United Arab Emirates holidays affect December 2025?
December 2025 contains 3 UAE federal holidays: Commemoration Day on Monday, December 1; National Day on Tuesday, December 2; National Day (day 2) on Wednesday, December 3. Banks and United Arab Emirates financial markets close on each of these days. Regional or industry-specific closures may add further non-working days for narrower contract definitions; layer them into the calculator's Advanced options if needed.
Why did the UAE workweek change in 2022?
Effective January 1, 2022, the UAE federal public sector moved from a Sunday-Thursday workweek (Fri-Sat weekend) to a Monday-Friday workweek with a half-day Friday closure for prayers. The private sector largely aligned to either Mon-Fri full weeks or Mon-Thu plus Fri half-day. This calculator uses the Saturday-Sunday weekend reflecting the post-reform federal-sector convention, which aligns UAE business days with European and US counterparties for cross-border invoicing and settlement. Free zone weekend rules may vary (e.g., ADGM and DIFC operate on standard western weekends).
How are Islamic lunar holidays handled in the calculator?
UAE Cabinet decrees announce the official holiday dates each year, with lunar holidays (Eid al-Fitr, Arafat Day, Eid al-Adha, Islamic New Year, Mawlid al-Nabawi) gazetted shortly before they fall. For years where the official decree has not yet been published, this calculator's data uses astronomical calculations and tags the entry with '(approximate)'. The published Cabinet decree may shift these dates by one day depending on the official moon-sighting (rouyat al-hilal). Always verify against the latest UAE Cabinet announcement for time-sensitive cross-border deadlines.
Why does the business-day count vary year to year?
Two things shift the monthly count for United Arab Emirates. First, the day of the week the first of the month lands on changes the count of each weekday. Second, UAE federal holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. December 2024 also had 20 working days, so the working capacity is unchanged year over year.
