Definition
Meaning
The practice of setting clocks forward by one hour in warmer months to extend evening daylight.
The system of time adjustment, officially known as Daylight Saving Time (DST), to make better use of natural daylight; often extended to refer to the time period when this system is in effect.
Linguistics
Semantic Notes
Often appears in the full form 'Daylight Saving Time' (abbreviated DST). The term 'saving' is singular, not 'savings', though the incorrect form is common. Refers to the system, not the act of saving daylight.
Dialectal Variation

Connotations
Neutral/systematic in both. Can carry connotations of seasonal change, government regulation, and debates over energy use or health impacts.
Frequency
More frequent in US media and conversation due to its federal and state-level legislative debates. In the UK, 'BST' is often used in official contexts.

FAQ
Frequently Asked Questions
The official term is 'daylight saving' (singular) in 'Daylight Saving Time'. However, the plural 'savings' is very common in informal American English.
Its original purpose was to make better use of daylight during the longer days of summer, theoretically saving energy by reducing the need for evening lighting. Modern justifications include promoting outdoor activity and reducing traffic accidents.
No, many countries near the equator do not, as daylight hours change little. Its use varies globally, and even within countries like the USA, some states (e.g., Arizona, Hawaii) do not observe it.
Use the mnemonic: 'Spring forward, fall back.' In spring, clocks move forward one hour (losing an hour). In autumn/fall, clocks move back one hour (gaining an hour).
