Diwali 2026 Wishes and Greeting Card AI Prompts: 4 Text and 4 Image Prompts

October 10, 2026•by Rohit Raj•11 min read

Diwali falls on Sunday, 8 November 2026, according to the Government of India's 2026 holiday list. In the days before it, phones fill with forwarded wishes that all look the same, and a short message written for one person stands out.

AI chatbots can help you write those personal wishes quickly, and image tools can design a warm greeting card. The catch is that AI image tools often misspell words inside pictures, especially names and Hindi text.

This guide gives you 4 text prompts for wishes to family, friends, colleagues and clients, and 4 image prompts for card designs with space left for your message. It also shows how to add the text yourself and how to size cards for WhatsApp and printing.

Diwali 2026 date and writing respectful wishes

The central government's 2026 list of holidays places Diwali (Deepavali) on Sunday, 8 November 2026, and some states also list a Deepavali holiday on Monday, 9 November. Puja timings and the dates of related days vary by region and panchang, so check a local calendar if your message mentions them.

Diwali is celebrated by Hindus, Sikhs, Jains and many others, and each community has its own traditions. For colleagues, clients or a mixed group, keep wishes about light, family, gratitude and new beginnings. Save specific religious references for people you know share them.

The image prompts below use festival settings such as diyas, rangoli, marigolds and lanterns, and they ask for no deities or religious figures. AI tools can render sacred figures inaccurately, which some people may find hurtful.

Why AI misspells text in images, and the workaround

An image model does not type letters. It paints pixels that look like what it has learned, and a word is a small, exact shape where one wrong stroke ruins it. Newer models handle short English phrases better, but names, long sentences and Devanagari still often come out garbled.

The reliable fix: generate the design with no text and an empty area, then add your message in a free editor such as your phone's photo editor or a design app like Canva. You choose the font, spell names correctly and can reuse one design for many people.

Step-by-Step: How to Use These Prompts

  1. 1For wishes, open ChatGPT or Gemini, copy a text prompt, and fill every square bracket with real details about the person.
  2. 2Pick the closest option and ask for small changes such as 'shorter' or 'more formal'. Read it once aloud before sending.
  3. 3For a card, copy an image prompt into an AI image tool such as ChatGPT or Gemini and set the aspect ratio if the tool offers one.
  4. 4Generate a few versions and choose one with a clean, empty area for text and no stray letters.
  5. 5Open the image in a free editor, add your wish in one or two readable fonts, then export it.

8 Copy-Ready Diwali Prompts

Copy a prompt, then use the button to open the tool it was written for.

Prompt 1: Personal Wish for a Family Member

Family

Written for: ChatGPT / Gemini

Write 4 short Diwali wishes for my [relation, e.g. nani / elder brother / mother-in-law], whose name is [name]. Details: [one or two real memories or things they do, e.g. makes the best besan laddoos, calls every Sunday]. Language: [English / Hindi in Devanagari / Hinglish in Roman script]. Tone: warm and respectful, not dramatic. Each wish under [40] words, at most [1] emoji. Mention the detail naturally and avoid lines like 'May this Diwali bring you endless joy'.

Open ChatGPT

Why this prompt works

The real memory is what makes a wish personal, so the prompt asks for it. 'Warm and respectful, not dramatic' avoids over-emotional lines, and banning one stock phrase steers the model away from forward-style wishes.

Make it yours

  • •Write to an elder in Hindi with 'aap' and a respectful closing.
  • •Add 'we will be together this year' or 'we are far apart this year' to change the mood.
  • •Ask for a two-line version to write inside a printed card.

Prompt 2: Playful Hinglish Wish for Friends

Friends, Hinglish

Written for: ChatGPT / Gemini

Write 5 fun Diwali wishes in Hinglish for my friend group on WhatsApp. Hindi words in Roman script, everyday spoken style. Inside jokes to use: [e.g. our 2 am chai runs, Rohan always burns the snacks]. Keep them light and kind, nothing that teases anyone harshly. Each under [30] words, at most [2] emojis. No film dialogues or song lyrics.

Open ChatGPT

Why this prompt works

Inside jokes make a group message feel written for that group. 'Light and kind' keeps teasing friendly, and 'no film dialogues or song lyrics' keeps it original rather than borrowing lines.

Make it yours

  • •Replace Hinglish with English if the group mixes languages.
  • •Add 'end with a plan to meet' for a message that doubles as an invite.
  • •Ask for one version suitable as a WhatsApp Status caption.

Prompt 3: Inclusive Wish for Colleagues

Workplace

Written for: ChatGPT / Gemini

Write 3 Diwali messages I can send to my team at [workplace type, e.g. a 20-person design studio]. Context: [one real team moment from this year, e.g. we shipped the new app in August]. Tone: friendly and professional. Keep the focus on light, gratitude and the year ahead, with no religious assumptions about readers. Each under [50] words, no emojis in the first option, one emoji allowed in the others.

Open ChatGPT

Why this prompt works

'No religious assumptions about readers' suits a mixed team. The real team moment turns a generic greeting into a thank-you, and varying the emoji rule gives you one formal option for email and lighter ones for chat.

Make it yours

  • •Add 'from me as team lead' to include a short thank-you for the team's work.
  • •Ask for a one-line version for a team channel.
  • •Add a holiday reminder, such as office closure dates, after the wish.

Prompt 4: Bilingual Greeting for Clients or Customers

Business

Written for: ChatGPT / Gemini

Write 3 Diwali greetings from my business, [business name and type, e.g. a home bakery in Indore], to regular customers. Write each greeting in English followed by a short Hindi version in Devanagari. Thank customers for their support this year. Tone: warm, simple and not salesy. Each English part under [40] words. Do not invent discounts or offers. Optional line about [festive orders / closure dates] at the end.

Open ChatGPT

Why this prompt works

'Not salesy' and 'do not invent discounts' stop the model from adding offers you never planned. The English-plus-Hindi format reaches more customers, and the optional last line keeps practical news separate from the greeting.

Make it yours

  • •Swap Hindi for Marathi, Gujarati or Tamil to match your customers.
  • •Remove the Hindi part for an email newsletter in English only.
  • •Ask a fluent speaker to check the Hindi before sending.

Prompt 5: Row of Diyas on Marigold Petals, Space Above

Classic Diya Card4:5

Written for: ChatGPT / Gemini

A Diwali greeting card background. A row of five lit clay diyas sits on a low brass tray scattered with orange and yellow marigold petals, in the lower third of the frame. Warm golden light, soft glowing bokeh in a deep maroon background. The upper two thirds is empty, smooth dark space for adding text later. Photorealistic, close-up, shallow depth of field. No text, no letters, no logos, no people, no religious figures.

Open ChatGPT

Why this prompt works

'In the lower third' and 'upper two thirds is empty' reserve space for your wish. Deep maroon keeps light text readable on top. The closing 'no text, no letters' line stops the tool from adding fake writing you would have to remove.

Make it yours

  • •Change maroon to deep navy for a cooler, modern card.
  • •Ask for 'one diya only, centred' for a minimal design.
  • •Swap the brass tray for a windowsill to suit a home photo style.

Prompt 6: Top-Down Rangoli with a Blank Centre

Rangoli Square1:1

Written for: ChatGPT / Gemini

Top-down view of a colourful rangoli pattern on a dark stone floor, made of coloured powder in pink, orange, yellow, green and white, with small lit diyas placed around the outer edge. The centre of the rangoli is a large plain circle of smooth white space, empty for adding text later. Symmetrical, crisp detail, warm evening light. No text, no letters, no symbols, no religious figures.

Open ChatGPT

Why this prompt works

'Top-down view' gives a flat, symmetrical pattern that crops neatly into a square. The 'large plain circle' in the centre is where your message goes, and 'no symbols' stops the tool from filling it with random marks.

Make it yours

  • •Use 'flower petal rangoli' instead of coloured powder for a softer look.
  • •Make the centre circle dark to suit white or gold text.
  • •Switch to 4:5 for an Instagram post, keeping the circle in the middle.

Prompt 7: Paper Lanterns at Dusk for WhatsApp Status

Vertical Status9:16

Written for: ChatGPT / Gemini

Vertical image of glowing paper lanterns in orange, red and gold hanging from the balcony of a home at dusk, with strings of small warm fairy lights. The sky is deep blue turning to purple. The lanterns and lights fill the middle of the frame; the top quarter and bottom quarter are calm, plain sky and dark wall, empty for text. Soft, warm, festive mood, realistic. No text, no letters, no people, no religious figures.

Open ChatGPT

Why this prompt works

A 9:16 image fills a phone screen in WhatsApp Status. Keeping the top and bottom quarters plain gives your text a calm area away from the busy lanterns, and app controls often sit near those edges anyway, so nothing important is hidden.

Make it yours

  • •Swap the balcony for a courtyard or a building entrance.
  • •Ask for star-shaped lanterns if you prefer that style.
  • •Change dusk to 'night with a few distant lights' for a darker card.

Prompt 8: Minimal Gold Line-Art Card

Minimal Design4:5

Written for: ChatGPT / Gemini

Minimal flat illustration for a Diwali greeting card. Thin gold line-art drawings of three diyas with small flames and a simple marigold garland along the bottom edge, on a plain deep green background. Lots of empty space in the centre and top for adding text later. Elegant, clean, modern, vector style, even margins. No text, no letters, no logos, no religious figures.

Open ChatGPT

Why this prompt works

'Flat illustration' and 'vector style' give clean edges that print well. The plain deep green background with 'lots of empty space' makes this the easiest design to add text to, and it suits clients and colleagues.

Make it yours

  • •Change deep green to ivory with gold lines for a lighter print card.
  • •Replace the garland with a line of hanging lanterns along the top.
  • •Ask for 1:1 if you will post it as a square.

Adding text, sharing on WhatsApp and printing

Add text in your editor, not in the prompt. Use one decorative font for 'Happy Diwali' and one plain font for the message, with light text on dark areas. Keep words away from the edges, and zoom out to thumbnail size to check they are still readable.

For sharing, 4:5 or 1:1 suits chats and Instagram, and 9:16 fills a phone screen in Status. WhatsApp's help pages say you can send photos in Standard or HD quality, and that Status uploads may look lower in quality than the original, so send cards with small text in HD.

For printing, check pixels. A 1024-pixel-wide image printed at 300 pixels per inch is only about 3.4 inches wide, while an A5 card needs roughly 1,750 pixels across. Print small cards or postcards, or ask your print shop what size your file supports.

Problems & Fixes

ProblemFix
The card still has random letters or fake writing.Repeat 'no text, no letters, no symbols' at the end of the prompt, regenerate, or cover the marks when you add your own text.
There is no empty space for my message.Say where the empty space is, such as 'upper two thirds empty', and ask for 'plain background' there.
The wishes sound like forwarded messages.Add a real memory or detail about the person and ban the phrases you keep seeing. Short and specific beats long and poetic.
The Hindi in the wish sounds stiff or has errors.Ask for 'everyday spoken Hindi' and have a fluent family member read it before you send it.

Pro Tips

  • •Make one design and personalise only the text for each person. It saves time and keeps every card consistent.
  • •Send personal wishes individually rather than broadcasting one message to everyone.
  • •Save your final design without text too, so you can reuse it next year.

Frequently Asked Questions

When is Diwali in 2026?

Diwali falls on Sunday, 8 November 2026, according to the Government of India's 2026 holiday list. Some states also list a holiday on Monday, 9 November. Puja timings differ by city, so check a local panchang.

Can AI write Diwali wishes in Hindi?

Yes, ChatGPT and Gemini can write Hindi in Devanagari or Hinglish in Roman script. Ask for everyday spoken Hindi, and have a fluent speaker check wishes for elders or clients, because small errors stand out in formal messages.

Why does my card say 'Happy Diwalli' or show strange letters?

Image models draw letters as shapes rather than typing them, so spelling often breaks, especially in longer text and Hindi. Generate the design without text and add your message in a free editor.

Is it okay to include gods or goddesses in an AI card?

These prompts avoid it on purpose. AI tools can depict sacred figures inaccurately, which some people may find hurtful. Diyas, rangoli, marigolds and lanterns convey the festival respectfully.
