Is 'off-hour' always hyphenated?

Yes, when used as a compound noun or adjective modifying another noun (e.g., off-hour schedule). It may sometimes appear as 'off hours' (two words) in phrases like 'during the off hours'.

Can 'off-hour' refer to a time during the weekend?

Yes, if the weekend is outside the standard operating or peak hours for a particular business or service, it can be described as an off-hour period.

What is the difference between 'off-hour' and 'off-peak'?

They are very similar. 'Off-peak' is more specific to times of lowest demand (e.g., for transport, electricity), while 'off-hour' can be any non-standard or less active period, not necessarily the absolute lowest point.

Is it correct to say 'an off-hour'?

Yes, it is a countable noun (e.g., 'I work several off-hours each week'). However, it is very frequently used in the plural ('off-hours') or in an adjectival form ('off-hour maintenance').
