Days of week

using this rule, users can configure widgets to be shown only on specific days of the week for example, only on fridays, when special offers are active on their websites also, users can configure a timezone, for checking the current day of the week, of the visitor for example, if the timezone is set to +2 00 gmt and in this timezone right now is friday 22 00, and the widget is set to be shown only on friday, the visitor from timezone +6 00 gmt will not see it, because in his timezone right is saturday 2 00 at the morning
