Dear @Anshu3 thanks for sharing it here.
Rekhta is no doubt one of the biggest celebration of urdu worldwide. I did not get the chance to attend it physically but I enjoy it Everytime online.
In the same manner (عالمی اردو کانفرنس کراچی) international Urdu conference Karachi is celebrated every year just like jashn-e-Rekhta. In which scholars, writers, poets and journalists from around the world come and attend the conference specially from India, Japan, Russia, UK, Denmark and other countries.
Here’s a glimpse of the conference from 2017 December.
And in last I want to share something for Rekhta, Delhi and Urdu conference Karachi for contributing towards development of Urdu.
سلیقے سے ہواؤں میں جو خوشبو گھول سکتے ہیں
ابھی کچھ لوگ باقی ہیں جو اردو بول سکتے ہیں
اردو جسے کہتے ہیں تہذیب کا چشمہ ہے
وہ شخص مہذب ہے جس کو یہ زباں آئی
