When does the Raksha Bandhan fall according to the Hindu calendar?

Hindu Calendar Basis:
Raksha Bandhan is celebrated on Shravan Poornima, the day of the full moon in the month of Shravana. The Hindu calendar is a lunisolar calendar, meaning festivals are determined by the phases of the moon combined with solar months.
Timing:
Since the lunar cycle does not align perfectly with the solar calendar, the date of Raksha Bandhan shifts each year but always falls in Shravana (July–August).
Religious Significance:
The festival symbolizes the bond of protection between brothers and sisters.
Sisters tie a rakhi (sacred thread) on their brothers’ wrists, praying for their well-being.
Brothers, in return, vow to protect their sisters and often give gifts.
Astrological Context:
Shravan Poornima is considered highly auspicious in Hindu tradition. It is also the day when other rituals like Upakarma (thread changing ceremony for Brahmins) and Hayagriva Jayanti are observed in different regions.
Examples of Dates:
In 2025, Raksha Bandhan will be celebrated on August 9.
In 2026, it falls on August 28 (Friday).
Why Full Moon (Poornima)?
The full moon is traditionally associated with completeness, prosperity, and blessings in Hindu belief. Celebrating Raksha Bandhan on Poornima enhances the spiritual and emotional significance of the bond between siblings.
