How should the Zakaat Nisaab of 12 months be calculated?

Answer

Payment of Zakaat is Waajib every 12 Islamic months. It is necessary to have a fixed due date every year although actual payment could be on any date after due date. If for example you calculated your Zakaat for the first time on 25 December 2018 (16th Rabiyuth Thaani 1440), then your Zakaat due date will be on 16 Rabiyuth Thaani every year.
