it was Saturday when her husband was free里的when可以换成that吗?不行的换请说明理由

不可以。
1. when引导定语从句,相当于on which = on Saturday,在定语从句her husband was free中做时间状语。
2. 如果用强调句型,则此句必须改写成:It was (加入on) Saturday when her husband was free.
因为强调句型的特点是:去掉it is/was和引导词that后,剩下是一个完整的句子。
但是楼主的例句做如上变化时,为:Her husband was free Saturday.
这就是一个错句,因为Saturday不能单独做时间状语。
