September 2026 keeps Bihar’s calendar simple — one compulsory holiday, two optional ones, and a widely celebrated festival that, despite what some calendars imply, isn’t actually an official day off. This Bihar Calendar September 2026 guide lists every public and restricted holiday for the month, clears up exactly which festivals close offices and which don’t, and confirms that for the third time this year, banks, government offices, and schools all get precisely the same number of days off.
Whether you searched for the Bihar Sarkar Calendar September 2026 to confirm Krishna Janmashtami’s date, you want to know if Haritalika Teej is actually a holiday, you’re a factory or workshop owner checking Vishwakarma Puja, or you simply need an accurate bank holiday count, this guide has been checked against Bihar’s 2026 state holiday notification and the standard RBI closure pattern for banks in the state.
Bihar Calendar September 2026 at a Glance
| Date | Day | Occasion | Holiday Type | Who Gets It Off |
|---|---|---|---|---|
| September 4, 2026 | Friday | Krishna Janmashtami | Public holiday | Government offices, banks, schools |
| September 12, 2026 | Saturday | Second Saturday | Bank holiday | Bank customers |
| September 17, 2026 | Thursday | Vishwakarma Puja | Restricted (optional) holiday | Only employees who choose it |
| September 25, 2026 | Friday | Anant Chaturdashi | Restricted (optional) holiday | Only employees who choose it |
| September 26, 2026 | Saturday | Fourth Saturday | Bank holiday | Bank customers |
Just one date this month closes everything by default — everything else on the list is either a standard Saturday or a holiday that individual employees have to actively choose to take.
The Festival That Isn’t Actually a Holiday
Here’s the detail worth flagging before anything else: Haritalika Teej, observed on September 14, 2026, is a significant fasting festival for many women across Bihar, marked with prayers to Goddess Parvati for marital wellbeing — but it doesn’t appear anywhere on Bihar’s official general, public, or restricted holiday list for 2026. It’s the same situation Makar Sankranti was in back in January: a festival that matters enormously to households across the state without being one the government has actually gazetted. If your workplace or your child’s school treats September 14 as a holiday, that’s a local or institutional decision, not a state-mandated one — worth confirming directly rather than assuming.
This is also the third month in 2026 — after May and July — where banks, government offices, and schools all land on exactly the same non-working days, since Krishna Janmashtami is the only compulsory closure and neither Vishwakarma Puja nor Anant Chaturdashi forces a blanket shutdown.
September 2026 Calendar Grid for Bihar
Bihar’s Weather in September 2026
September marks the tail end of Bihar’s monsoon, and the pattern shifts noticeably as the month goes on. Early September still carries a reasonable chance of rain and high humidity left over from August, but by the third week, the southwest monsoon typically begins withdrawing from the Indo-Gangetic plains, and Bihar sees fewer and lighter showers as a result. Daytime temperatures ease into the low 30s, and the air gradually loses some of the heaviness that defined July and August. It’s a reasonable month for outdoor Janmashtami celebrations at temples in Patna and elsewhere, though a light rain contingency is still worth keeping in mind for the first half of the month before the monsoon fully retreats.
Krishna Janmashtami 2026 in Bihar — September 4 (Friday)
Krishna Janmashtami marks the birth of Lord Krishna and is observed at midnight with fasting, devotional singing, and elaborate decoration of temples and home shrines across Bihar, particularly in Patna, Gaya, and other cities with significant Krishna temples. It’s listed among Bihar’s public holidays, closing government offices, banks, and schools statewide, alongside major nationwide celebrations at pilgrimage centres like Mathura and Vrindavan that draw devotees from across the country.
Vishwakarma Puja 2026 in Bihar — September 17 (Thursday)
Vishwakarma Puja honours Lord Vishwakarma, the divine architect and craftsman in Hindu tradition, and is observed particularly by factories, workshops, technical institutions, and anyone working with tools or machinery — mechanics, engineers, and manufacturing units across Bihar typically hold small pujas for their equipment and workspaces on this day. It sits on Bihar’s restricted holiday list, meaning individual employees can choose to take it as one of their allotted optional holidays, but it doesn’t close government offices, banks, or schools by default.
Anant Chaturdashi 2026 — September 25 (Friday)
Anant Chaturdashi falls on the fourteenth day of the bright fortnight of Bhadrapada and traditionally marks the conclusion of the Ganesh Utsav period, observed with the immersion (visarjan) of Ganesh idols and prayers to Lord Vishnu in his Anant (infinite) form. Like Vishwakarma Puja, it’s a restricted holiday on Bihar’s calendar — available to employees who want to use it as an optional day off, but not a blanket closure.
Bihar’s Holiday Categories, Explained
September is a clean, compact example of how Bihar’s tiers interact when there’s no general-holiday-only date in the mix:
| Category | Decided By | Applies To | September 2026 Examples |
|---|---|---|---|
| General holidays | Government of Bihar | Government offices and schools | None this month |
| Public / festival holidays | Government of Bihar | Government offices, banks, and schools | Krishna Janmashtami (Sep 4) |
| Restricted (optional) holidays | Employee’s own choice | Only employees who select the date | Vishwakarma Puja (Sep 17), Anant Chaturdashi (Sep 25) |
With no general-only date this month, there’s nothing to create a split between banks and government offices — the same pattern seen in May and July.
Bihar Bank Holidays — September 2026
Banks in Bihar follow the Negotiable Instruments Act, 1881, and the RBI’s standing second-and-fourth-Saturday rule. Here’s how September 2026 lines up:
| Date | Day | Reason |
|---|---|---|
| September 4, 2026 | Friday | Krishna Janmashtami |
| September 6, 2026 | Sunday | Weekly holiday |
| September 12, 2026 | Saturday | Second Saturday |
| September 13, 2026 | Sunday | Weekly holiday |
| September 20, 2026 | Sunday | Weekly holiday |
| September 26, 2026 | Saturday | Fourth Saturday |
| September 27, 2026 | Sunday | Weekly holiday |
| Category | Count |
|---|---|
| Sundays | 4 |
| Second & fourth Saturdays | 2 |
| Festival closure on an extra weekday (Krishna Janmashtami) | 1 |
| Total non-working days for banks | 7 |
Seven non-working days puts September alongside February and June as one of the calmer months of the year for Bihar’s banking calendar, well short of March’s high of twelve. Branches stay shut on all seven dates, though ATMs, UPI, and net banking continue running normally.
Bihar School Holidays — September 2026
Bihar’s Education Department calendar marks just one date for government and government-aided schools, including Sanskrit, Urdu, and Madrasa institutions, in September:
| Date | Day | Occasion |
|---|---|---|
| September 4, 2026 | Friday | Krishna Janmashtami |
Vishwakarma Puja and Anant Chaturdashi don’t appear here since they’re restricted rather than general school holidays, and Haritalika Teej isn’t on the official calendar at all. Private and CBSE-affiliated schools frequently run internal assessments or unit tests through September, so it’s worth checking your child’s specific school notice board alongside this list.
Everyone’s Calendar Matches Again — For the Third Time This Year
May was the first month where banks, government offices, and schools shared identical closure dates, and July repeated that pattern with an entirely empty calendar. September makes it three, with Krishna Janmashtami as the only compulsory date and nothing general-only to create a gap between banks and government offices. Secretariat and Directorate offices in Patna, which already treat every Saturday as a day off under their five-day week, still end up slightly ahead at 9 non-working days once all four Saturdays in September are factored in alongside Krishna Janmashtami.
Looking Ahead: October Brings Bihar’s Own Festival
Late September is effectively the countdown to Jivitputrika, also called Jitiya, one of Bihar’s most significant and distinctly homegrown festivals — a multi-day fast observed by mothers for their sons’ wellbeing, falling just days after September ends. It’s a good reminder that Bihar’s calendar picks up considerably in October, running straight into Durga Puja and the start of the Chhath Puja season shortly after.
