In Hindi, “Happy Diwali” is commonly said as “शुभ दीपावली” (Shubh Deepavali).
- शुभ (Shubh) means auspicious or good.
- दीपावली (Deepavali) is another name for Diwali, which literally means a row of lights.
You can also say “दीपावली की हार्दिक शुभकामनाएँ” (Deepavali ki hardik shubhkamnayein), which translates to “Heartfelt best wishes for Diwali.” This is a more formal way of wishing someone well during the Diwali festival.
