Casablanca to San Juan Time

Casablanca (Morocco) is North Africa's gateway to European and African markets, with key industries in automotive, aerospace, phosphates, agriculture, and tourism. San Juan (Puerto Rico) is a US territory with pharmaceutical and tech manufacturing, known for pharmaceuticals, medical devices, electronics, and tourism. With a 5-hour time difference, professionals frequently schedule cross-border calls between these two cities for international trade, remote team collaboration, and client meetings.

Scheduling Meetings Between Casablanca and San Juan

The 5-hour difference between Casablanca and San Juan requires careful scheduling. The best overlap window is typically 2–4 hours when both cities are within working hours. Moroccan business hours are typically 9 AM–6 PM, with Casablanca as the primary business and financial center. Puerto Rican business hours are typically 8 AM–5 PM, with a bilingual (English/Spanish) workforce. Teams often designate specific "overlap hours" for real-time collaboration and use asynchronous communication (Slack, email, recorded video) for the rest of the day.

Daylight Saving Time Considerations

Casablanca observes Daylight Saving Time (WET/WEST), but San Juan does not — it stays on AST year-round. This means the time difference between Casablanca and San Juan changes by 1 hour when Casablanca switches clocks. During Morocco's summer, the gap is 4–6 hours instead of the standard 5 hours. Mark DST transition dates on your calendar to avoid missed meetings.

Collaboration Tools & Workflow

The 5-hour gap between Casablanca and San Juan means teams get roughly half a day of overlapping work hours. Successful cross-timezone teams typically batch synchronous activities (standups, reviews, planning) into the overlap window and reserve solo deep work for non-overlapping hours. Tools like Loom for async video updates, Slack with status indicators showing each team's local time, and shared Notion docs help bridge the gap. Many teams adopt a "follow-the-sun" workflow where handoffs happen at the edges of each team's workday.

Remote Work Between Casablanca & San Juan

Casablanca, a key city in Morocco, and San Juan, a key city in Puerto Rico, represent a common corridor for distributed teams navigating a 5-hour time difference. Remote workers and freelancers operating between these cities should plan their day around the overlap window — typically the late morning for one city and early morning or late afternoon for the other. Using a world clock widget, setting Slack status with local time, and blocking "no-meeting" deep work hours outside the overlap are essential practices for productive cross-timezone remote collaboration between Casablanca and San Juan.

WET (WET/WEST) stands for the timezone used in Casablanca, Morocco (UTC+1). AST (AST) is the timezone used in San Juan, Puerto Rico (UTC-4). Casablanca is 5 hours ahead of San Juan.

To convert WET to AST, subtract 5 hours from WET time. For example, WET 9:00 AM = AST 4:00 AM.
