CRC 1955, p. 105

“S 15 Holika-dahana (Sayahnavyapini — it should be observed on second half of purnima at night), Dolayatra (Bengal & Orissa) (covering 4 ghatikas before sunrise of the day of festival), Holi — on the day after Holikadahana.” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 105. The hour the row gives for the rite ("it should be observed on second half of purnima at night") is not tested: sāyāhna alone settles the day.
