Significance of Hindu New Year: The first day of the Chaitra month, which usually occurs in March or April, is designated as the Hindu New Year. It marks the arrival of spring, a season of rebirth and revitalization for the natural world. Hindu mythology holds that this is the day that the universe's creator, Lord Brahma, began his work. For Hindus, it's a lucky time to start new projects, make big decisions, and ask for blessings for a successful next year.
