Hartalika Teej is observed every year on the third day of the bright fortnight (Shukla Paksha) of the Hindu month of Bhadrapada, according to NDTV. The day is marked by a vrat (fast) and a puja performed by devotees.
NDTV’s coverage focuses on the calendar basis for the observance—specifically the timing within the Bhadrapada month and the tithi (lunar day) that devotees follow. The outlet also frames the day in terms of the vrat and the overall puja schedule, including reference to the puja muhurat and vrat procedure, though the provided excerpts only explicitly confirm the date structure and festival positioning.
Across the two NDTV items provided, the central details presented are consistent: Hartalika Teej falls on the third day of the bright fortnight in Bhadrapada.
