Government Holidays in Tamil Nadu:
Each year, the Government of Tamil Nadu officially announces its list of public holidays, under the Negotiable Instruments Act of 1881. These are applicable to state government offices, banks (including cooperative), and affiliated corporations. Historically, this list has included around 23 to 24 days, covering national holidays and state‑specific festivals for example, in 2025, 23 holidays were declared, including Pongal, Thiruvalluvar Day, and Deepavali
Historical Background and Release Process
Traditionally, government holidays have been gazetted well before the start of each year. For instance, the TN government formally released the 2024 list in November 2023, and similarly the 2025 list in November 2024. The process involves a government order (G.O.) issued by the Chief Secretary, following templates under the central framework of the 1881 Act.
As a result, citizens and institutions can plan calendars, payrolls, school programs, and public services with clarity. Even so, banks observe certain holidays like April 1 (annual bank-closing day) as special cases, while other government offices remain open.
Standard Inclusions: National and Regional Festivals
Government‑wide holidays typically include:
- National Days: New Year’s Day (January 1), Republic Day, Independence Day, and Gandhi Jayanthi.
- State‑specific festivals: Pongal, Thiruvalluvar Day, Uzhavar Thirunal (farmer’s day), Tamil New Year, Mattu Pongal and Kaanum Pongal, Thai Poosam.
- Religious observances: Good Friday, Telugu New Year (Ugadi), Ramzan (Idu’l Fitr), Bakrid (Eid al‑Adha), Muharram, Krishna Jayanthi, Vinayagar Chaturthi, Milad‑un‑Nabi, Ayutha Pooja, Vijayadasami (Dussehra), Deepavali, and Christmas.
“For example, in 2025, the government has scheduled holidays on January 14 (Pongal), January 15 (Thiruvalluvar/Mattu Pongal), and October 2, which marks both Vandijaya Dasami and Gandhi Jayanthi.
Exclusions: Optional and Unofficial Observances
The state government does not declare several culturally significant festivals as public holidays, even though they are deeply celebrated. These include festivals such as Karthigai Deepam, Aadi Perukku, Thaipusam, and Madras Day. Despite their popularity, they are relegated to cultural observance rather than statutory closure.
Additionally, caste‑or community‑specific commemorations like Thevar Jayanthi (October 30 in Madurai and surrounding districts) or Devendrar Jayanthi (September 11) are generally not public holidays, despite local observance and support from particular political organizations.
Local and District‑Level Holidays
District collectors or local authorities may declare holidays to commemorate temple festivals, local anniversaries, or religious ceremonies.. For instance, in 2025, Tenkasi district declared two additional holidays on April 7 and April 11 for the consecration of a temple and the Panguni Uttara festival ( Ref : tenkasi.nic.in ). Such district holidays are issued by the Collector’s office through a separate G.O.
Reddit users from Thoothukudi, Thiruvannamalai, Chengalpattu, and Coimbatore districts have previously pointed out district‑level leaves for Thai Poosam, Vaikasi Visakam, Kantha Sashti, Aadi Pooram, Panimaya Madha festival, and district-specific deity celebrations. Although not universal across Tamil Nadu, these holidays remain very real for affected local populations.
Impacts and Coordination
Public and local holidays play important roles in education planning, scheduling government tasks, and ensuring efficient staffing. Because Saturdays and Sundays are also officially non‑working days for government offices, holiday lists help complete the annual closure calendar. Schools often adjust term dates or exam schedules when district level holidays are observed separately. For instance, multiple districts declared school holidays in July 2025 to mark Aadi Thiruvathirai, Aadi Amavasai, and Aadipura festivals even though these did not feature in the state‑wide official list.
