Cotton Silk Wool, It does not harm to do some research before posting. There are some factual errors in your post: 1. Before Bikram Sambat became our official Sambat, we used Saka Sambat, not Nepal Sambat. 2. No, Mahendra and BP-Team did not submit Nepal Sambat, Pali, and Newari as our official date, script and language when joining the UN on 14 Dec. 1955. This rather weak argument has been used time and again by the advocates of Nepal Sambat. There are disputes regarding Nepal Sambat. In some documents, it is regarded as Maha Chin Sambat. Precisely for this reason, Nepal's historians, even those who belong to the group that celebrates Nepal Sambat such as Dhana Bajra bajracharya, never directly advocated in favor of Nepal Sambat. During the 2030s decade, there was a proxy war on Nepal's print media between the people for and against the Nepal Sambat. This has been chronicled by historian Mahesh Chandra Regmi in his monograph, Nepal Sambat ko Anauchitya Ko Sambandha Ma. It is true that some old merchants of Kathmandu Valley keep their books on Nepal Sambat. But it is only in the valley. In Tarai region, they use Janak Sambat. You move further north, they use Buddha Sambat. We have many Sambats in Nepal.If we make Nepal Sambat our official Sambat, then it will only favor the valley's majority. So instead of seeking recognition as an official Sambat by politicizing the issue, let's just celebrate it. Look at the the other side of politicizing the ethnic/cultural things: Nepal will soon be divided into Sambats/languages/cultures/groups, and that's going to prove disastrous to our already politically divided nation.
