The festival of colours, played on the day after Holika Dahan on Phalguna Purnima.
The tithi window is the period during which this festival's defining lunar phase is active. Times are in Hatcho-muta local clock.
Holi marks the arrival of spring and the triumph of devotion over evil — the burning of Holika and the protection of Prahlad by Vishnu. In Krishna tradition, Holi celebrates the playful colour-throwing between Krishna and Radha in Vrindavan.
Holi is observed on the civil day where Phalguna Shukla Purnima is present at sunrise — the day after the previous evening's Holika Dahan (which itself is performed during Pradosha Kala on the Purnima).
Computed for Hatcho-muta (Asia/Tokyo) using local sunrise, sunset and astronomical positions.
