“Mesadi — Cadaka puja (Bengal), Bahag Bihu (Assam), Cheiraoba (Manipur), Visu (T. C. State), Vaisakhi (on the samkramana day commencing from sunrise).” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 106. “The following festivals are observed according to the day of Sun's transit into rasis (Ravi-samkramana). For this purpose the day has been taken to begin from midnight, i.e., when the samkramana takes place after midnight, the festival relating to the samkramana is to be observed on the following day.” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 106. The other names in the row (Cadaka puja, Bahag Bihu, Cheiraoba, Visu) are regional observances and wait with the regional rows.
