Nepal observes a national day of mourning for victims of a flash flood disaster on the 13th day after the tragedy. The day is marked in keeping with traditional Hindu practice that marks the thirteenth day following a death.

On this 13th day, official symbols reflect the mourning. BBC reports that flags fly at half-mast, describing it as the last day of the Hindu mourning period. The Hindu also notes that the observance continues through the 13-day mourning cycle, aligning national recognition of the disaster’s victims with the religious calendar.

Overall, both outlets agree on the timing and religious basis of the mourning: it takes place on day 13 after the flash floods and represents the end of the Hindu mourning period.
