Origin of Day Light Savings practice

Banjamin Franklin who coined the proverb ""Early to bed, and early to rise, makes a man healthy, wealthy and wise", published a letter (An Economical Project, a discourse on the thrift of natural versus artificial lighting.) to Paris citizens on how to save candles by raising earlier and use morning sunlight. This concept was later used as a way to save energy and thus came in the practice of "day Light savings". More
