What is passive voice?
When a verb performs an action for the subject of a phrase rather than the other way around, this is known as the passive voice.
To convert an active voice sentence into passive voice, the focus is laid upon the action instead of the subject. Now, the subject which was "we" is receiving the action instead of performing it.
Thus, "Democracy day is celebrated on falgun seven by us." is a sentence written in passive voice.
