Punjab
The major language spoken in the Punjab is Punjabi. In the Indian Punjab this is written in the Gurmukhi script. Pakistan uses the Shahmukhi script, that is closer to Urdu script. Hindi, written in the Devanagri script, is used widely in the Indian states of Himanchal Pradesh and Haryana. Several dialects of Punjabi are spoken in the different regions. The Majhi dialect is considered to be textbook Punjabi and is shared by both countries.
Punjabi language
Both federal and state laws specify the use of Punjabi in the field of education. The state of Punjab uses the Three Language Formula, and Punjabi is required to be either the medium of instruction, or one of the three languages learnt in all schools in Punjab. Punjabi is also a compulsory language in Haryana, and other states with a significant Punjabi speaking minority are required to offer Punjabi medium education.
