Lagos is the same time as Barcelona during winter, or 1 hour behind during summer DST. When it's 12:00 PM in Barcelona (summer), it's 11:00 AM in Lagos. Nigeria does not observe DST.
Barcelona uses CET/CEST while Lagos uses WAT (West Africa Time).
Optimal window: 9:00 AM - 6:00 PM Barcelona time works well year-round. The minimal time difference makes business communication convenient.
Lagos is Africa's largest city and Nigeria's economic hub with strong trade ties to Spain.
