Is Tomorrow A Holiday In Iran? The Latest Status On Emergency Closures (Farda Ta'til Ast Ya Na)
The question "Farda Ta'til Ast Ya Na?" (Is tomorrow a holiday or not?) is one of the most frequently searched phrases in Iran, especially during the winter months. As of today, Friday, December 26, 2025 (5 Dey 1404 in the Jalali calendar), the status for tomorrow, Saturday, December 27, 2025 (6 Dey 1404), is complex: it is not a fixed national holiday, but there is a high probability of emergency closures in major metropolitan areas.
The official weekend in Iran is Friday, meaning most government offices, schools, and businesses are already closed today. However, Saturday is a regular working day for most sectors. The key factor determining a surprise closure—a "ta'til"—is almost always an emergency announcement related to severe weather, flu outbreaks, or, most commonly, the critical issue of air pollution (Aloudegi Hava) in cities like Tehran, Isfahan, and Alborz province.
The Two Types of 'Ta'til': Fixed Holidays vs. Emergency Closures
Understanding the holiday structure in Iran requires distinguishing between fixed national holidays and unpredictable emergency announcements. The Iranian calendar (Jalali calendar) governs all official dates, which often vary significantly from the Gregorian calendar.
Fixed National Holidays: Is Saturday, December 27, 2025, on the Calendar?
Saturday, December 27, 2025 (6 Dey 1404), does not fall on a major, fixed national holiday on the 2025 calendar. Major fixed holidays are determined by religious (Islamic) and national events, such as:
- Nowruz (Persian New Year): A multi-day national celebration starting around March 21.
- Eid al-Fitr & Eid al-Adha: Major Islamic holidays, which shift annually on the Gregorian calendar.
- Ashura & Tasu'a: Days of mourning for the martyrdom of Imam Hussein.
- Islamic Revolution Day: February 11.
Since the date falls outside these major events, any closure for tomorrow would be an unscheduled, localized decision made by provincial authorities.
Unscheduled Emergency Closures: The 'Aloudegi Hava' Crisis
The most common reason for an unexpected "ta'til" in the winter months of the Iranian year (especially in the months of Azar and Dey, corresponding to November through January) is dangerously high levels of air pollution.
The severity of this crisis has led to the establishment of the Air Pollution Emergency Task Force (Kar-grooh-e Ezterar-e Aloudegi Hava) in provinces like Tehran. This task force is responsible for monitoring the Air Quality Index (AQI) and making last-minute decisions on closures.
Recent reports confirm that emergency school and university closures due to severe air pollution have been a recurring event throughout December 2025. This includes closures in:
- Tehran Province
- Alborz Province (Karaj)
- Isfahan Province
- Other major industrial and densely populated provinces.
These closures are often announced late in the evening (after 8 PM local time) to take effect the following day, creating high suspense around the "Farda Ta'til Ast Ya Na" question.
Latest Status for Saturday, December 27, 2025 (6 Dey 1404)
As of the latest updates on Friday, December 26, 2025, there has been no official, confirmed announcement of a widespread national holiday or a definitive emergency closure for Saturday, December 27, 2025.
However, the situation is highly fluid, and local news outlets are reporting a strong possibility of closures in the capital and surrounding areas due to a combination of factors, including:
- Air Quality Forecast: Persistent thermal inversion layers trap pollutants, keeping the Air Quality Index (AQI) in the "unhealthy" or "hazardous" range.
- Weather Conditions: Recent forecasts have indicated unfavorable atmospheric conditions, including heavy snow and rain in some regions, which can also trigger localized school closures.
- Influenza/COVID-19 Concerns: While air pollution is the primary driver, local officials have also cited the spread of infectious diseases as a supplemental reason for closures in the past.
The final decision rests with the provincial crisis management committees. If a closure is announced, it typically affects all levels of schools (elementary, middle, and high school) and sometimes universities, while government offices and banks may remain open or operate with reduced hours.
Navigating the Closures: Key Entities and How to Check
For anyone living or traveling in Iran, knowing which entities are responsible for announcing a "ta'til" is crucial for planning. The system is decentralized, with provincial authorities holding the power for emergency closures.
Key Entities and Terms to Monitor
To get the most reliable, up-to-the-minute information, you must monitor official sources, usually through state news agencies or the provincial government websites. The relevant entities and terms include:
- Kar-grooh-e Ezterar-e Aloudegi Hava: The Air Pollution Emergency Task Force, the main decision-maker for air pollution closures.
- Ostan-dari (استانداری): The Governorship of the Province (e.g., Tehran Governorship), which issues the final decree.
- Vezarat-e Amoozesh va Parvaresh (وزارت آموزش و پرورش): The Ministry of Education, which confirms school-specific closures.
- AQI (Air Quality Index): The metric used to justify the closure decision. Levels above 150 are typically cause for concern.
- Inversion (وارونگی هوا): The meteorological phenomenon where cold air is trapped beneath warm air, preventing pollutants from dispersing.
- Dey (دی): The Iranian month (Dec/Jan) when air pollution is historically at its worst.
In summary, while Saturday, December 27, 2025, is not a fixed national holiday, the high alert status for air pollution in Tehran and other metropolitan centers means the decision for a "ta'til" is pending. Residents are advised to check official news channels late on Friday evening for the definitive status.
The Broader Context: Why Air Pollution is a December Crisis
The recurring school and office closures due to air pollution are not just a matter of convenience; they reflect a severe public health crisis in Iran’s major cities. The problem is exacerbated during the cold season (Dey) due to several factors:
1. Thermal Inversion: This natural weather pattern traps the polluted air close to the ground, especially in the geographically constrained Tehran basin.
2. Increased Fuel Consumption: Lower temperatures lead to a surge in the use of domestic heaters and power plants, many of which rely on low-quality, heavy fuel oil (Mazut) that emits high levels of pollutants. The use of Mazut is a major point of public debate and political contention.
3. Vehicle Emissions: An aging fleet of vehicles and heavy traffic congestion contribute significantly to the smog. Traffic restrictions and alternating license plate schemes (like the "Odd-Even" plan) are often implemented alongside closures but have limited long-term impact.
The frequent closures highlight the government’s reliance on short-term fixes rather than long-term environmental solutions, affecting the academic year and the economy. Between 2021 and December 2025, Iran has experienced the equivalent of an entire academic year lost to virtual schooling and closures due to these crises. This ongoing situation ensures the phrase "Farda Ta'til Ast Ya Na" will remain a top search query for the foreseeable future.
