Currency exchange markets are open 24 hours a day on weekdays, which means the best time to buy Georgian Lari is any day of the week except on weekends. That said, 3 PM - 4 PM UTC is often a good time to buy Georgian Lari because market liquidity in the New York and London exchanges tends to peak at around this time. Also, bear in mind that transactions executed on a Friday might not clear until the following Monday morning when the market next opens.
