Occasion posters

Onam poster maker for Kerala businesses

Onam is Kerala’s harvest festival: pookalam flower carpets at the door, new clothes, and the Onam sadya that fills every restaurant. For shops in Kerala and Malayali communities abroad, it is the busiest week of the year.

UniPostudio is made by CODEZYAI in Kochi, so Onam is on the calendar for brands in India with a reminder 10 days before Thiruvonam, and the occasion sheet turns your brand kit into an Onam poster in four sizes.

The festival builds over the days before Thiruvonam, starting at Atham. Dates are checked against published panchang and government lists.

What to post for Onam

  • Ten days before: your Onam collection, sadya bookings or offer, with a booking deadline.
  • The days leading up: kasavu sarees and mundu, flowers for pookalam, delivery cut-offs.
  • Uthradom, the eve: last-minute hours and takeaway sadya slots.
  • Thiruvonam: a greeting, “Happy Onam” or ഓണാശംസകൾ, and nothing pushy.
  • After: a thank-you post and photos of your own pookalam.

Onam poster ideas by business

  • Restaurants and caterers: sadya booking and takeaway, with a Google Business Profile post using the Book or Order button.
  • Textile and saree shops: the photo style for the kasavu collection.
  • Jewellers: an Onam offer in the minimal style with your contact line.
  • Florists: pookalam flower orders, with collection times.
  • Electronics and home appliances: festival offers, in the bold style.
  • Salons: bridal and festive bookings before Thiruvonam.

Malayalam captions

UniPostudio’s interface is available in Malayalam, alongside Hindi, Bengali, Tamil, Telugu, Kannada and English. Character counting is Unicode-aware, so Malayalam captions are measured correctly. On YouTube, descriptions are limited to 5,000 bytes, and Malayalam reaches that well before 5,000 characters; the composer counts it for you. Support email and help docs are in English.

A simple caption: “എല്ലാവർക്കും ഓണാശംസകൾ! സദ്യ ബുക്കിംഗ് ആരംഭിച്ചു.” (Happy Onam to everyone! Sadya bookings are open.)

How to make an Onam poster in UniPostudio

  • Open the calendar. The occasion is already on it for brands in that market, with a reminder on the suggested post day.
  • Click the occasion to open its occasion sheet, and choose a poster or a text post.
  • Pick a style (minimal, bold, festive or photo) and write your headline and offer.
  • Your brand kit is applied: brand name, logo (a light version on dark designs), brand colours and a contact line such as your website.
  • UniPostudio renders the poster in all four sizes at once.
  • Send it to the composer, write or generate a caption, adjust it per channel and schedule it.

Frequently asked questions

When is Onam in 2027?

Thiruvonam falls on Sunday 12 September 2027. In 2026 it was on 26 August.

When should I start posting for Onam?

UniPostudio suggests about 10 days before Thiruvonam, 2 September for 2027, and sends a reminder on that day.

Can I write Onam captions in Malayalam?

Yes. Captions can be in any language, Malayalam is counted correctly against channel limits, and the interface itself is available in Malayalam.

What does it cost in India?

Classic is ₹499 a month plus 18% GST, charged in rupees through Razorpay, with a 30-day trial and no card. Occasion posters are unlimited. See pricing.

Does the app generate the pookalam picture?

It can, if you choose. Where AI artwork is switched on, you describe the scene, such as a pookalam or a sadya on banana leaves, and our image provider’s AI makes the picture behind your logo and text, which are drawn on top exactly as you typed them. An AI picture costs credits; designed posters stay unlimited. Posters with AI artwork are marked as AI-generated, and labelled as such where the platform supports it, such as TikTok. You see a preview and can change the text before anything is posted.
