⚠️ Common Mistakes
El estrés es un problema diario en mi vida.
El estrés es un problema cotidiano en mi vida.
While not technically wrong, 'cotidiano' is much more natural. It describes the *type* of problem (a common, routine one), not that you experience the exact same stress every single day.
Tomo mi pastilla cotidiana.
Tomo mi pastilla diaria.
For scheduled, once-a-day actions like taking medicine, 'diario' is the correct word. 'Cotidiana' would sound strange, as it's about the general nature of things, not a specific frequency.

Frequently Asked Questions
Can I use 'diario' and 'cotidiano' interchangeably?
Sometimes you can get away with it, but it's not ideal. 'Diario' is best for things on a strict 24-hour cycle (a daily report, a daily pill). 'Cotidiano' is much better for describing the general feeling, routine, or quality of daily life (everyday stress, everyday language). Using the wrong one can sound a bit unnatural.
Is 'vida diaria' or 'vida cotidiana' more common?
'Vida cotidiana' is far more common and idiomatic when talking about 'everyday life' as a concept. 'Vida diaria' is not wrong, but it sounds more literal, like 'life on a daily basis'. For the general concept, stick with 'vida cotidiana'.
