San Juan & Dili — Business & Scheduling Guide
San Juan (Puerto Rico) is a US territory with pharmaceutical and tech manufacturing, with key industries in pharmaceuticals, medical devices, electronics, and tourism. Dili (Timor-Leste) is a young Southeast Asian nation with oil and gas revenues, known for oil and gas, coffee, agriculture, and tourism. With a 13-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 San Juan and Dili
With Dili 13 hours ahead of San Juan, there is minimal overlap in standard business hours. Most teams alternate meeting times to share the burden of early-morning or late-evening calls fairly. Puerto Rican business hours are typically 8 AM–5 PM, with a bilingual (English/Spanish) workforce. Timorese business hours are typically 8 AM–5 PM, with Dili as the business center. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.
Daylight Saving Time Considerations
Neither San Juan nor Dili observes Daylight Saving Time — San Juan stays on AST and Dili stays on TLT year-round. This makes scheduling between these two cities simpler, as the 13-hour time difference remains constant throughout the year with no DST surprises.
Collaboration Tools & Workflow
With a 13-hour time difference, San Juan and Dili teams operate in a near "follow-the-sun" model. When one team logs off, the other picks up — enabling near-24-hour productivity on shared projects. The key challenge is handoff quality: teams should document decisions in shared tools (Notion, Confluence, Linear), record video updates with Loom, and write thorough pull request descriptions. Weekly all-hands meetings require someone to take an early morning or late evening call, so the best practice is to rotate this burden fairly between San Juan and Dili.
Remote Work Between San Juan & Dili
San Juan, a key city in Puerto Rico, and Dili, a key city in Timor-Leste, represent a common corridor for distributed teams navigating a 13-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 San Juan and Dili.
