Festival Arithmetic: How 25 UK Leave Days Fit Four India Trips in 2026

There are two kinds of leave days: the ones you spend and the ones you wish you'd saved. In 2026, the Indian festival calendar handed UK-based travellers a useful masterclass in spending them well. With Diwali just behind us on 8 November and Christmas the only fixed point left, the year's ledger is nearly closed. Here's how a standard 25-day annual leave allowance, plus the UK bank holidays, stretched to four India trips—and what to copy when the next cycle comes around.

The fixed points: eight UK bank holidays

Start with the dates you don't have to beg for. In England and Wales, 2026's bank holidays ran: New Year's Day (1 January), Good Friday (3 April), Easter Monday (6 April), early May (4 May), spring bank holiday (25 May), summer bank holiday (31 August), Christmas Day (25 December) and the Boxing Day substitute (28 December). Scotland has its own quirks, including 2 January, so check your nation's list before you promise anyone a long weekend.

The lesson is simple: bank holidays are anchors, not trips. Two consecutive days off can save a flight, but they rarely cover a full Indian festival. You need annual leave as the engine.

Holi: the four-day smash-and-grab

Holi fell on 3-4 March 2026, midweek and miles from any UK bank holiday. That made it a pure annual-leave play: four days off, a Thursday-night departure if you could get one, and a Monday back at your desk looking faintly pink behind the ears. Crowds in Delhi, Mathura and Vrindavan were busy but manageable; flights were cheaper than the Diwali window and hotels were still in shoulder-season mode.

For first-time visitors, Holi is a brilliant introduction: short, visual, and over before festival fatigue sets in. For British-Indian families, it's trickier. If your relatives expect you for the colour and the gujiya, a four-day trip can feel like a flying visit. The trap is treating Holi as a family reunion when it's really a long weekend with pigment.

Onam: the bank-holiday bridge

Onam's main day, Thiruvonam, landed around 26 August 2026, with the summer bank holiday on 31 August doing some of the heavy lifting. That combination made Kerala unusually efficient: five leave days plus the bank holiday gave a workable seven-night run. The catch was cost. Kerala's hoteliers know exactly when Onam is, and houseboat and resort rates climb accordingly.

Book five to six months ahead if you want a decent backwater boat or a family-friendly stay in Kochi. Crowds are domestic-heavy, which is part of the charm—but it also means trains and hill-station roads fill up. Onam suits first-timers who want culture without the full-throttle chaos of a northern festival, and returning families with Kerala roots who can combine the sadya with actual family time rather than a whistle-stop tour.

Durga Puja: the leave-hungry one

Durga Puja in 2026 ran roughly 17-21 October, and it is the festival that eats annual leave for breakfast. There's no UK bank holiday anywhere near it, so you need seven or eight days to do Kolkata properly. The reward is pandal-hopping after dark, a city that feels like one enormous open-air art project, and food stalls on every corner.

The crowd levels are not for the faint-hearted. If you dislike queuing, skip the biggest pandals at peak hours and go early morning or late night. Book flights four to six months out and hotels in Kolkata five months ahead; the good central ones vanish first. This is a returning-family favourite, especially for Bengali diaspora households, but first-timers should treat it as an advanced-level festival rather than an easy introduction.

Diwali: the family default

Diwali fell on 8 November 2026, a Sunday, which was both a gift and a trap. The weekend did some of the work, but every British-Indian family seemed to have the same idea. Flights spiked, hotels in Jaipur and Udaipur tightened, and the group chat filled with demands to attend three different parties in two cities.

The sweet spot was four or five leave days around the weekend, booked six to eight months ahead. Diwali is the default family festival for many households, so the expectation trap is real: if you skip it, someone will notice. The trick is to decide early whether you're going for the family or for the fireworks, and to say so before the tickets are bought.

The booking clock: what 2026 taught us

Holi: eight to ten weeks ahead was fine for flights, though colour-run hotels in tourist hotspots needed earlier attention. Onam: five to six months for Kerala, especially houseboats. Durga Puja: four to six months for flights, five for Kolkata hotels. Diwali: six to eight months, full stop. Set flight alerts in the spring and don't wait for a 'deal' in October.

The family-expectation ledger

Four trips in one year is not just a logistics exercise; it's a diplomatic one. The safest pattern is to pick two 'family' festivals (usually Diwali and one regional one) and two 'experience' trips (Holi, Onam or Durga Puja). Tell relatives which is which early. If you're doing Holi but missing Diwali, say it in September, not the week before. Video calls are not a substitute for presence, but they do buy goodwill.

Who should copy which window

First-time visitors: Holi for a short, bright introduction; Onam for a gentler cultural deep-dive. British-Indian families returning home: Diwali for the default reunion; Durga Puja if Kolkata is the ancestral anchor. Tight leave allowances: Onam, because the August bank holiday does free labour. Crowd-averse travellers: Holi, provided you avoid the famous Mathura circuit on the main day.

The final tally

Four trips, 25 leave days, eight bank holidays, and a lot of careful calendar-watching. The 2026 arithmetic wasn't magic—it was just early booking, honest conversations and a refusal to treat every festival as a compulsory family event. With Christmas now the only fixed point left on the UK calendar, the next window is already taking shape. The lesson stands: match the festival to your leave, not your leave to the loudest group chat.
