Is the word horários the same in Brazilian and European Portuguese?

Yes

The word "horários" is identical in both Brazilian and European Portuguese in terms of spelling, grammar, and fundamental meaning (referring to schedules, timetables, or office hours). The only differences are phonological (pronunciation):

• Vowels: In Brazilian Portuguese, unstressed vowels are often more open and clearly articulated. In European Portuguese, unstressed vowels are frequently "reduced" or swallowed, making the word sound shorter and more closed.
• Sibilance: In most regions of Brazil, the "s" at the end of "horários" is pronounced as a /z/ sound (like the English 'z'). In Portugal, the "s" is typically pronounced as a /ʃ/ sound (like the English 'sh').
