Baisakhi Vaisakhi Waheguru Vaheguru

Baisakhi Vaisakhi Waheguru Vaheguru

In recent years I have started to question the way some words are spelled when written in English. I have grown up writing and even chanting "Waheguru"  (with a "W") and saying "Baisakhi" with "B".  I have since changed my habit however though  I do wonder how so many people started spelling both these words this way. When you read the Gurmukhi the first letter clearly starts with a "ਵ" (ਵਾਹਿਗੁਰੂ / ਸਾਖੀ ), which makes the sound "V" not "B" or ਬ. You don’t see the word written as ਬਸਾਖੀ. I thought this was important particularly for chanting / meditating with the Vaheguru Mantra. Chanting with a "W" (Waheguru") is quite different then with a "V".

What do you think about this?
