Timor-Leste operates on GMT+9 year-round without daylight saving time adjustments.

The United States dollar serves as official currency alongside small centavo coins minted specifically for Timor-Leste. Indonesian rupiah circulates informally in border areas and Oecusse exclave.

Credit cards see acceptance only in international hotels and select Dili restaurants. Cash dominates all transactions. Currency exchange services cluster along Avenida de Portugal in Dili. Travelers should arrive with clean, undamaged US dollar bills, as torn or heavily worn notes face rejection.
Portuguese and Tetum hold official language status. Tetum functions as the lingua franca, blending Austronesian grammar with Portuguese vocabulary absorbed over four centuries. Indonesian remains widely understood, particularly among the population educated before 1999. English proficiency concentrates in tourism industry workers, NGO staff, and younger urban residents educated post-independence. Government services operate primarily in Portuguese and Tetum. Rural areas see minimal English comprehension. The Catholic Church conducts services in Tetum with Portuguese elements. Indonesian language newspapers still circulate alongside Portuguese and Tetum publications.

Water from taps requires boiling or filtration throughout the country. The Dili municipal system delivers untreated or partially treated water dependent on seasonal flow. Sealed bottled water costs 0.50-1.00 USD for 1.5 liters. Accommodation outside cities may lack running water entirely, providing stored rainwater or well water for washing. Ice in drinks carries the same risk as tap water. Visitors should carry water purification tablets when traveling to rural areas where bottled water becomes unavailable.
