Yes! Arequipa and Lima are both in Peru and use Peru Time (PET, UTC-5) year-round. When it's 12:00 PM in Arequipa, it's also 12:00 PM in Lima.
Peru does not observe daylight saving time, so the time remains synchronized between these cities throughout the year.
Any time works! Since both cities share the same timezone, you can call during any business hours without conversion.
Arequipa is about 1,000 km southeast of Lima. Flights take approximately 1.5 hours, while driving takes about 14-16 hours via the Pan-American Highway.
