Sec 390

A court will take judicial notice that a particular date was Sunday.3 But when the statute prescribes that Sunday closes with sun-setting, there must be proof that the contract was in that part of the day in which it would have been illegal.4 The date may be contradicted by parol, and it may be shown that though a writing is dated on a secular day, the real date is Sunday.5

Sec 391

In several states the duration of Sunday, so far as concerns the limitation now before us, is defined by statute. In such states the statutory prescriptions are to control.6
