Happy Holi 2018! Today begins the spring festival celebrated in the Indian subcontinent and all over the world by Hindus. The date represents the arrival of spring and the end of winter, while also serving as a thanksgiving time for spiritual renewal of relationships.

Like the Jewish Purim holiday before it, Holi begins the night before since the Hindu calendar, like the Hebrew calendar, begins days on the night before. The evening beginning Holi is called Purnima, which means full Moon day.

While Holi has become increasingly secularized with globalism, the original religious underpinnings behind the holiday memorialize the way that Holika, the sister of the demon king Hiranyakashipu, was killed in the fire, which symbolized the struggle of good over evil. The night before the color festival of Holi, bonfires are held by Hindus to symbolize this cleansing of bad thoughts.

On the day that has been associated as "Holi," Indians and non-Indians throw colored powders (cornstarch powder mixed with food coloring and other variants) at each other to celebrate. However, there are other ways to make the powders, some less environmentally friendly, which has become a concern, reports the India Environment Portal.

In more recent years, Holi has spread across the world, including countries with large Indian immigrant populations such as Suriname, Guyana, Trinidad and Tobago, South Africa, Malaysia, the United Kingdom, the United States, Canada, Mauritius and Fiji. Here, the practice of Holi has been excitedly adopted by non-Hindu celebrants.
