关于p1注册用地址住满至少30个月

规定小一P1 注册用的地址必须住至少30 个月，这个30个月到底从哪天开始算，统一是从当年小一第一阶段报名注册起始日计算还是个人不同阶段报名注册登记日开始计算？

MOE recognises that some families are unable to remain at the address used for registration for the entire duration of the child's primary school studies. Even so, a child who gains priority admission through their distance category is required to reside at the address used for registration for　at least 30 months　from the start of the P1 Registration Exercise on 1 July 2020. If this condition is not met, MOE reserves the right to transfer the child to another school with vacancies, as the priority admission to the first school was based on the declared address used for registration.

今年的话，moe网站是这么写的，那么如果今年在2c阶段1公里内抽签报上的名，是按2020年8月3日2c注册报名日开始起算需要住满30个月？还是从2020年7月1日开始算30个月即可，即任何阶段报名都按2020年7月1日这一天算起，住满30个月？
