Diwali and Halloween are overlapping for the first time since 2016 ...

For Famizun Nisha and her family, Diwali is going to look a little different this year.

In a rare overlap, the Hindu festival of lights will be celebrated from October 31 to November 1 — coinciding with Halloween for the first time since 2016.

Ms Nisha, a Fiji-Indian Muslim who lives in Forest Lake, south-west of Brisbane, said the fusion of cultures is a daily reality.

Married to a Punjabi Sikh, she balances her own heritage with her husband's, raising their seven-year-old son, Ekvir.

"We've been doing this since he was born … and as he's growing up and forming core memories," she said.

Although Halloween isn't a religious observance in their traditions, Ms Nisha embraces it as an annual family event, going trick-or-treating with Ekvir.

"He went a month ahead to get his Halloween outfit, and he's super excited about it," she says.

"We usually go to Brookwater, where Halloween is celebrated on a large scale."

This year, she plans to differentiate between the two celebrations by spending October 31 celebrating Halloween with her son, and November 1 celebrating Diwali.

"You can't over shine them both, because … the kids will get confused," she says.

Diwali is commonly celebrated among Hindus, but Jessi Singh, an American-Indian living in Melbourne, said the festival was celebrated widely across India by many religious communities today.

"Back in India, most streets and homes are always decked out with colours," Mr Singh said.

Mr Singh lived in the United States before migrating to Melbourne in 2008, and said that while Halloween wasn't as commonly celebrated in Australia as it was in the US, his family had found ways to continue their traditions.

"Halloween is a very big deal in America and since having kids, it's an even bigger deal [for us] now," he said.

"My kids are very excited, they have been planning their Halloween costumes for the last five months and I've even set up a candy station in our house."

For Mr Singh, Diwali and Halloween falling on the same day is "double the fun" and an opportunity to bring both sides of his family together.

"I think having both Halloween and Diwali is the perfect way to celebrate different cultures together," he said.

This year the fusion of Diwali and Halloween is extending beyond family gatherings, with workplaces also joining in on the festivities.

IFC Global Logistics and Warehousing, an international supply chain company located in Altona, in Melbourne's south-west, has embraced the cultural blend with their own event dubbed "Diwaloween."

Diwaloween aimed to incorporate traditions from both Halloween and Diwali, as a way to explore "unity in diversity".

"A big part of IFC's culture involves celebrating a wide range of traditions and festivals, and this commitment plays a key role in shaping our positive workplace environment," said IFC employee and Diwaloween organiser Arun Mechineni.

Their event last Friday featured a unique pumpkin rangoli, symbolising the fusion of Diwali and Halloween traditions, and employees embraced the theme with costume choices, blending elements of both cultures.

"Some even wore sarees and kurtas paired with Halloween masks, creatively blending both cultures," fellow employee and event organiser Harika Kallalu said.

Mr Mechineni said the purpose of the event had been to acknowledge and understand the diverse cultures among co-workers.

"These celebrations contribute to a stronger sense of community," he said.

"Employees feel more connected not only to their own cultural roots but also to those of their colleagues."
