In the UK between the last Sunday in March and the last Sunday in October Greenwich Mean Time goes forward one hour to take advantage of there being more light in the evening than in the morning during the Summer. Which means the clocks went back one hour today. The aim is to give the like of farmers more time to do their work during the Summer.
This moving of time and the hours of the day are agreed upon to allow us to all work to the same timescale. It is a practical use of the time that we have each day, by dividing it into portions that can be allocated and measured. This is without getting into the physics of relative Spacetime.
This brings up the point of how we allocate our time during each day. Many of us will spend a lot of our time on social media or watchng TV or a streaming service like Netflix, which could be seen as a good use of our time or not. A better question would be, is the quality of how we spend time good?
If you spend most of a weekend binge watching a series on Netflix the hours spent on that is high in quantity but I would argue that it is low in quality. Spending the weekend with friends, you could argue, is higher in quality. It depends on what you value, which is different for each of us.
Doing an audit of how we spend our time and thinking about the benefits of each thing we do can mean we move the arch of our lives towards a more meaningful existence.
