Umrah was made obligatory in the ninth year of Hijrah, and it is permissible to perform Umrah throughout the year, meaning that there is no specific time for it except during the days of Hajj. Umrah is different from Hajj, as Hajj is one of the pillars of Islam and is obligatory for every able Muslim. It also has a specific time for performing its rituals, which is the opposite of Umrah.
