As depicted in Hindu mythology, Diwali signifies the return of Lord Rama to his kingdom Ayodhya after completing 14 years of exile and then defeating the tyrant Ravana who had captured Rama's wife Sita.
The festival of Diwali is also called 'Deepawali' or 'Festival of Lights' ('Deep' means 'light' in Hindi). The festival marks the Hindu New Year and is celebrated over 5 days. Houses are brightly lit with decorative lights and the entrance porch is usually decorated by a colorful mosaic known as 'Rangoli'.
Friends and relatives visit one another to exchange good wishes and sweets. Children enjoy this festival the most as they look forward to the evening, as once the sun sets, it's time to light up the sky with colorful fireworks.
