Good to know
- On a Sunday. The list also names Uzhavar Thirunal (17 January); Independence Day (15 August); Milad-un-Nabi (Prophet's Birthday) (15 August). These fall on a Sunday, so they are not counted here.
- Annexure has 24 rows. Row 9, Annual Closing of Bank Accounts on Thursday 1 April 2027, applies only to commercial and co-operative banks and is excluded from government office holidays by the G.O. (not in items).
- Row 16 Independence Day and row 17 Milad-un-Nabi share one merged date cell: 15.08.2027 (Sunday). So Milad-un-Nabi is listed on 15 Aug 2027 in the official table, not 15 Sep.
- Items with a Saturday date are inside items because the G.O. still lists them as public holidays: Thiruvalluvar Day 16 Jan, May Day 1 May, Vinayakar Chathurthi 4 Sep, Gandhi Jayanthi 2 Oct, Vijaya Dasami 9 Oct, Christmas 25 Dec.
- Optional holidays. The G.O. lists public holidays only; no optional/restricted holidays are in it.
- Source difference. Milad-un-Nabi: official G.O. table shows 15.08.2027 (same cell as Independence Day); Kalvimani shows 15.09.2027 - treated as an error, official used.
- Source difference. Deepavali: TN G.O. 28 Oct 2027 (Thursday) vs central government list 29 Oct 2027 (Friday); state's own date used.
- Festivals tied to the moon, such as the Eid festivals and Muharram, can move by a day. Any change is announced at short notice.
Building your company's Tamil Nadu calendar
If you run HR for a company with staff in Tamil Nadu, treat this list as your starting point. Add the national days your policy gives, decide whether you offer floating holidays, say in writing what happens when a holiday falls on a weekend, and publish the final calendar before the year begins. If you have offices in several states, keep one calendar for each.
For the central government list, see Central Government holiday list 2027. The Tamil Nadu list for 2026 is at Tamil Nadu holiday list 2026.
