I have seen the reference most recently when it comes to payment systems, but “24-7-365” is becoming widely used to connote something that is always open. It is short for “24 hours a day, seven days a week, 365 weeks a year.”
But there aren’t 365 weeks in a year. There are 52 weeks in a year. Thus, this expression is nonsensical.
A correct expression would be 24-7-52: 24 hours a day, 7 days a week, 52 weeks a year.
An easier, equally correct expression would be simply 24-365: 24 hours a day, 365 days a year.
A less accurate, but seemingly acceptable expression, would be simply 24-7, with an understanding that seven days per week means every week, and not just some weeks.
Also an option, for those more verbal than numerical: always-open.
That is all.
