Business hours vary, depending on what sort of establishment you're discussing. Generally, Sunday is the week's least busy day, so if it's the only time you can visit, call your intended destination beforehand so you're not disappointed.

As a general rule, pub hours run from 11am to 11pm daily, except Sunday, when places close a bit earlier.

On national holidays, most businesses close or schedule abbreviated hours. Commonly, these days include:
