Gentle Reminder: Daylight Saving Time Starts Tomorrow

March 7, 2026

Key Takeaways Copied to clipboard!

  • Benjamin Franklin's supposed proposal for Daylight Saving Time was actually a satire mocking Parisian habits, not a serious recommendation for energy conservation. 
  • The earliest serious proposals for Daylight Saving Time came from George Hudson (1895) and William Winnett (1907), primarily to provide more sunlit leisure time after work. 
  • The most powerful, though often unstated, reason for the continuation of Daylight Saving Time is the economic benefit derived from increased consumer spending during the extra hour of evening daylight in the summer months.

  • Key Takeaway: Benjamin Franklin’s famous proposal regarding daylight saving was a satire suggesting firing cannons at sunrise to save candle wax.
  • Summary: Franklin is often incorrectly credited with inventing Daylight Saving Time based on conserving candles. His 1784 letter was actually satire aimed at the nocturnal habits of Parisians. He suggested waking people with cannons to save 64 million pounds of candle wax over six months.

  • Key Takeaway: Serious proposals for Daylight Saving Time originated independently from George Hudson (1895) and William Winnett (1907) for summer leisure time.
  • Summary: The first serious propositions came a century after Franklin, from a New Zealander and an Englishman. Both suggested the change only for summer to allow for additional sunlit leisure time after work. This schedule keeps morning wake-up times aligned with sunrise while maximizing evening daylight.
Farmer Myths Debunked

  • Key Takeaway: Farmers are often vocal opponents of Daylight Saving Time because changing the clock inconveniences them when selling crops to city dwellers.
  • Summary: The popular perception that Daylight Saving Time benefits farmers is false; farmers are among the most vocal opponents. Tasks like milking are done at sunrise regardless of the clock, and changing the clock disrupts schedules for selling produce. The only cogent farm-related arguments involve dairy cows needing 24-hour milking intervals and safety concerns moving heavy equipment in early morning light.
Electricity Conservation Claims

  • Key Takeaway: The official reason for Daylight Saving Time, electricity conservation, yields statistically insignificant results today due to increased air conditioning and electronics use.
  • Summary: The idea that residential power usage is reduced by delaying the need for lights was true during the 1970s oil crisis. However, modern ubiquitous air conditioning often outweighs lighting savings, leading to mixed or negligible national results. Any possible energy savings derived from Daylight Saving Time is statistically insignificant.
The Real Economic Driver

  • Key Takeaway: The primary reason Daylight Saving Time persists is the significant financial boost it provides to recreational and retail industries.
  • Summary: Strong reasons for policy continuation usually involve money exchanged at the cash register, not utility bills. An extra hour of evening daylight encourages people to spend money on dining, recreation like golf, and shopping. Extensions to the DST period have been strongly supported by industries like golf and candy due to increased sales.
