The effects of 4 sowing dates (15February, 1March, 15March and 1April) on phenology and thermal indices of 3 varieties (Tilottama, Rama and Savitri) of sesame (Sesamum indicum L.) was studied in split-plot design with 3 replications at Bidhan Chandra Krishi Viswavidyalaya, Jaguli, Nadia, West Bengal during pre-kharif (summer) season of 2017.Delay in sowing of sesame from 15 February to 1 April shortened the duration of sesame by 24.8 days (100.2 vs. 75.4 days).Mean summed growing degree days (GDD), heliothermal unit (HTU) and photothermal unit (PTU) for entire life cycle of sesame were recorded as 1584.87oC day, 10871.8oC hour and 19607.98oC hour, respectively. The correlation studies revealed that GDD (r = -0.893**) and PTU (r = -0.898**) during flower initiation to capsule initiation showed negative (P<0.01) effect on seed yield of sesame in New Alluvial Zone of West Bengal.
