Pahar (Hindi/Nepali: पहर, Urdu:پہر), which is more commonly pronounced paher, is a traditional unit of time used in India, Pakistan, Nepal and Bangladesh. One pahar nominally equals three hours, and there are eight pahars in a day. In India, the measure is primarily used in North India.
Pahar/pehar/peher is derived from Sanskrit word prahar which is an ancient unit of time in India.
Traditionally, night and day were each allocated four pahars, or "watches." The first pahar of the day (or din pahar) was timed to begin at sunrise, and the first pahar of the night (raat pahar) was timed to begin at sunset.
This meant that in the winter the daytime pahars were shorter than the nighttime pahars, and the opposite was true in summer. The pahars were exactly equal on the equinoxes. Thus, the length of the traditional pahar varied from about 2.5 hours to 3.5 hours in the Indo-Gangetic plains.
Each pahar of a 24-hour day-night cycle has a specific name and number. The first pahar of the day, known as pehla pahar (Hindustani: pehla, meaning first), corresponds to the early morning. The second pahar is called do-pahar (Hindustani: do, meaning second). In the common speech of North India, Pakistan and Nepal, dopahar (दोपहर or دوپہر) has come to be the generic term for afternoon or midday. The third pahar is called seh pahar (Persian:seh, meaning three) and has generically come to mean evening, though the term is less commonly used than shaam.
The poet-saint Kabir mentions pahar in one of his dohas:
पाँच पहर धंधे गया, तीन पहर गया सोय ।
एक पहर हरि नाम बिन, मुक्ति कैसे होय ॥
[You] went to work for five pahars, slept for the remaining three pahars. How will you attain salvation without chanting the holy name of the Lord for at least one pahar?

In traditional Hindu society(as in of time when Sanatan Dharma was only major religion in Indian Subcontinent), each prahar was associated with certain task or Karma, which were to be finished in that prahar only. Each varna had specified karma in which atleast one prahar(mostly first or last day prahar) was dedicated to sadhna(God worship).
