Guru Nanak Dev Ji's Parkash is disputed between 3 Dates
Friday, Katak Sudi 15 Pooranmashi, 1526 Bikrami (Lunar)
Saturday, Vaisakh Sudi 3, 1526 Bikrami (Lunar) (Not Pooranmashi)
Monday, 1 Vaisakh, 1526 Bikrami (Solar Date) (Also Pooranmashi)
There is debate on this issue, I recommend reading the document mentioned in the OP.
Also PLS, Benti for everyone, when referring to Gurpuabs, pls use Bikrami or Mool Nanakshahi dates, don't use English dates as they are not accurate as the original.
Serious question though, how would one use a Dori Kirpan practically? Like how would it be used?
I think thats why some people say its just for show because maybe you can't use it well? I wouldn't know.
Oh, so it's not a made-up saakhi? Even if it were, it would be good. It sounds vaguely like the saakhi of Bhai Banno.
I agree that it is unreasonable to demand discounts of shopkeepers because "it's for a religious purpose". They can't verify that. You're trading on your long beard to make the other guy think you're "religious". You're just setting it up for unscrupulous people with beards to come by and abuse it, which then gets found out, and then people lose faith in Sikhs and Sikhi.
On the other hand, it would be OK for a gurdwara to put out the call for construction materials, legal services, accounting services, medical services (free medical camps). Then people can verify it's for a religious purpose because they're giving directly to the gurdwara. And then sawmill owners can drop off wood at the gurdwara, marble showroom owners can drop off marble, etc. Or people in fields not in demand can buy the stuff (possibly at cost) and have it delivered to the gurdwara.
