Paraguay Summer Time (PYST) was the daylight saving time previously observed in Paraguay during the summer months. It operated at UTC−3, advancing the country's standard time by one hour from its usual UTC−4 winter time. Also known as Paraguay Daylight Time, PYST typically began in October and ended in March, making better use of evening daylight during the longer summer days.
Importance and Global Use of PYST
PYST played an important role in optimizing daylight hours across Paraguay, helping to reduce energy consumption in the evenings and providing extended daylight for business, education, and social activities. This extra evening light supported safer travel, boosted leisure opportunities, and benefited the economy during the summer months.
On a broader level, PYST helped align Paraguay's schedule with neighboring countries like Argentina and parts of Brazil, which also operated on UTC−3 during the summer. This synchronization made it easier to manage international trade, transportation, and cross-border communication, supporting regional economic cooperation and improving logistical efficiency.
