As the calendar turns and the air grows cooler, the question on many lips is, when is Diwali this year? The festival of lights, known as Deepavali, is one of the most significant and widely celebrated occasions in the Hindu calendar, marking a profound spiritual victory over darkness. While the date shifts annually according to the lunisolar Vikram Samvat calendar, the anticipation and preparation begin well in advance, making it essential to pinpoint the exact timing for the upcoming year.
Diwali 2025: The Date on the Gregorian Calendar
For the current year, the primary day of celebration, known as Lakshmi Puja, is scheduled for Sunday, November 1, 2025. This date corresponds to the new moon day, or Amavasya, of the Hindu month of Kartik. The festivities, however, are not confined to a single evening; the festival officially spans five days, beginning with Dhanteras on October 28, 2025, and culminating with Bhai Dooj on November 3, 2025. This extended period allows for a series of rituals, family gatherings, and community events that build toward the grand finale.
Understanding the Lunisolar Calendar
The reason Diwali’s date changes each year lies in its unique calculation. The festival is based on the Hindu lunisolar calendar, which combines the cycles of the moon and the sun. Diwali is observed on the 15th day of the dark fortnight (Krishna Paksha) in the month of Kartik. Because the lunar month is approximately 11 days shorter than the solar year, an extra month, or Adhik Maas, is added to the calendar every few years to keep the lunar and solar cycles in sync. This intercalary month causes the lunar date to shift slightly against the Gregorian solar calendar, resulting in Diwali falling anywhere between mid-October and mid-November.
Regional Variations and Celebratory Timelines
While the core dates remain consistent across India, the specific day of worship can vary by region due to local traditions and calendar interpretations. In some parts of North India, the main puja might be performed a day earlier on Sunday, October 31, 2025. Similarly, in Gujarat, the festival marks the start of the new financial year, and the focus on Lakshmi, the goddess of wealth, is especially pronounced. These nuances highlight the cultural richness of the festival, where a single event is woven into the fabric of diverse local customs.
The Five Days of Diwali 2025
To fully appreciate the festival, it helps to understand the sequence of the five-day celebration. Each day holds specific significance and rituals, creating a journey of preparation, reflection, and joy. Below is a detailed breakdown of the key dates for the 2025 festival period.
