Questions
Are the results legally binding?
No. Hasiby applies the published rules to the figures you enter. Your contract, your employer's policies and a court can all change the outcome, so treat the result as an estimate and the explainer as a starting point.
Where do the rules come from?
From the laws and official calculators of each country: the Saudi Labor Law and the Ministry of Human Resources, the UAE Labour Law and MOHRE, ZATCA and the Federal Tax Authority for VAT, and the Umm al-Qura calendar for Hijri dates. Each page lists its sources.
Is my data stored?
No. Calculations run in your browser and nothing you enter is sent to a server. The link you copy carries the figures, so share it only with people who may see them.
