Fun fact, Spain’s unusual schedule is partially due to timezones! The country itself is literally an hour late, and is kinda stuck in either an idyllic summer lifestyle or a vicious labor cycle, depending on how you look at it.

Glance at a map and you’ll realise that Spain – sitting, as it does, along the same longitude as the UK, Portugal and Morocco – should be in Greenwich Mean Time (GMT). But Spain goes by Central European Time (CET), putting it in sync with the Serbian capital Belgrade, more than 2,500km east of Madrid.

Being 60 minutes behind the correct time zone means the sun rises later and sets later, bestowing Spain with gloriously long summer evenings and 10pm sunsets.

But for many Spaniards, living in the wrong time zone has resulted in sleep deprivation and decreased productivity. The typical Spanish work day begins at 9am; after a two-hour lunch break between 2 and 4pm, employees return to work, ending their day around 8pm. The later working hours force Spaniards to save their social lives for the late hours. Prime-time television doesn’t start until 10:30pm.

Spaniards have traditionally coped with their late nights by taking a mid-morning coffee break and a two-hour lunch break, giving them the opportunity to enjoy one of the country’s most famous traditions: the siesta.

Basically, they still take breaks (that have pre-timezone cultural roots) in large part because they start too early and because they work and eat and sleep late… but they work and eat and sleep late because they start too early and take long breaks and the sun sets late… so they get less sleep and need more breaks and naps to get through the long day…
