What is the simplest way to explain Diwali to a young child's teacher?

Describe it as a major Hindu festival marking the victory of light over darkness and good over evil, celebrated with lamps, family gatherings, sweets, and often fireworks, similar in scale to how a teacher might think of a major winter holiday.

Why doesn't Diwali fall on the same date every year?

Diwali follows the lunar Hindu calendar rather than the fixed Gregorian calendar, so its date shifts each year, usually landing somewhere in October or November.

Should a note to school mention a specific date for this year's Diwali?

Yes, since the date changes annually, it is worth checking the current year's date before sending the note rather than relying on last year's, and including it directly so the teacher can mark it if a student will be absent or celebrating.

Explaining Diwali to Your Kids' US Teachers: a Short Parent-Teacher Primer

A short note to a teacher before Diwali saves a lot of back-and-forth, especially if a child will miss school or wants to bring something in to share. Here is a factual primer parents can send as is or paraphrase.

What Diwali marks

Diwali, also called the Festival of Lights, is one of the most widely celebrated Hindu festivals, and it is also observed by Sikh, Jain, and some Buddhist communities with their own significance attached. At its core it marks the symbolic victory of light over darkness and good over evil. Families light diyas (small oil lamps), decorate their homes, gather for meals, exchange sweets, and in many households burst fireworks as part of the celebration.

Why the date moves every year

Diwali is set by the lunar Hindu calendar, not the fixed Gregorian one, so the date shifts from year to year rather than landing on a fixed day. It usually falls somewhere in October or November. Checking the current year’s date before sending a note to school, rather than reusing last year’s, avoids sending the wrong information.

A simple classroom-appropriate framing

For younger classrooms, comparing it loosely to how other cultures mark a major holiday with lights, family time, and food tends to land well without oversimplifying the religious meaning. A line like “it’s a bit like our winter holidays, with lights and family visits instead of snow” gives a teacher an easy way to place it. Parents are the ones best placed to decide how much detail fits their child’s classroom and age group, and how much to mention about specific deities or mythology behind the festival.

If the family is planning a trip to India or a home celebration that keeps a child out of school, naming the date early and framing it as a religious observance, similar to how a school already handles other cultural or religious absences, usually gets a straightforward response from most US and UK schools. Offering to send a photo or a small sweet for the class afterward is optional but often appreciated.

A sample note parents can copy

“Dear [Teacher’s name], our family celebrates Diwali, the Hindu festival of lights, on [date] this year. [Child’s name] may be tired or excused for part of the day, as we’ll be up late for the main celebration the night before. Diwali marks the victory of light over darkness and is one of our family’s most important holidays of the year, similar in importance to how other families might treat a major religious holiday. Happy to answer any questions. Thank you, [Parent’s name].”

Schools that already recognize Diwali

New York City public schools added Diwali as an official school holiday starting in 2023, following years of advocacy from Hindu, Sikh, and Jain community groups, and a handful of other US districts with large South Asian populations have followed with similar policies since. Checking a school district’s specific calendar and absence policy before assuming a note is even necessary is worth doing, since Diwali may already be a recognized non-attendance day locally.

Bringing something in for the class

If a child wants to share something at school, individually wrapped, shelf-stable sweets, small packaged mithai or fudge-style barfi, tend to clear school allergy and food-safety policies more easily than homemade items, which some schools restrict outright. Checking with the teacher about the class’s specific allergy restrictions before bringing anything in avoids a wasted trip, and a lot of teachers appreciate a one-line explanation card taped to the container so kids can read what they’re trying.

Where to get this year’s date
