Almerimarlife.com founder Chris Marshall claimed although individuals arrive at work by around 09:00 CET, they will not have eaten breakfast until the middle of the morning.
Furthermore, lunch is at around 14:30, while an evening meal might be at 20:30 to 21:00, the expert added.
He stated people work between 17:00 and 20:00 and consider this to be the afternoon, so if a delivery or visitor is expected at this time of day, it will be after 17:00.
NotesinSpanish.com director Ben Curtis recently noted people in Spain wait until later than 22:00 before going out at the weekend.
"If Spanish friends say to you 'we'll give you a call after work' – don't expect a phone call till 21:00 to 21:30 in the evening," Mr Marshall added.
Individuals who insist on keeping the hours of their home country will find themselves eating in expatriate restaurants with other foreigners and are unlikely to integrate as successfully as those who do not, he pointed out.
