As we are nearing the end of the first week back on normal time, I thought I would analyze the progression of Daylight Saving Time.

Since they keep increasing the number of weeks spent on DST, I wondered how long it would take before there was only DST and no more standard time. I think a lot of people would be happy if they didn’t have to change their clocks twice a year, especially these people.

Here is a history of DST in the US, starting with the beginning of the USA in 1776 (approximately).

As you can see, there was no DST for a while, then it started, then it increased, then it increased again.

If it keeps increasing linearly, it might look like this:

From that, I estimate that there will be only DST starting in the year 2147.

But you may have noticed that the increases are increasing in frequency, which suggests an exponential relationship rather than linear.

That estimate is 2033, which means only 23 more years of switching clocks.

I will not miss that hassle at all.
