The 40 days festival in Jammu and Kashmir is known as "Chillai Kalan." It is not a festival in the traditional sense but rather the harshest 40-day winter period in the Kashmir Valley, starting from December 21 to January 29 each year.
During Chillai Kalan, temperatures often drop significantly, leading to freezing weather and sometimes heavy snowfall. This period is marked by its harsh winter conditions but is also a time of beauty and celebration, as the snow-covered landscape becomes a sight to behold
