“Temporal landmarks could help assuage that terrible feeling of time speeding up as you age. In what researchers call the ‘calendar effect’, we use milestones to form and retain memories – so university students, say, have much better recall of events near the start or end of term, even when you allow for the emotional highs and lows of freshers’ week or graduation. The more landmarks, the less risk of suddenly realising you’ve no idea where last year went.” — Oliver Burkeman, “This Column Will Change Your Life: The Importance of Temporal Landmarks, The Guardian

As this is published, it’s a Tuesday. What does Tuesday represent? Taco Tuesday, trash and recycling day on my particular street, the second day of the work week, weight circuit day in my fitness schedule, and really not much else that would differentiate it from Wednesday or Thursday this week. And this Tuesday is a lot like last Tuesday and the one before that. They all blend together, don’t they? That’s why life feels routine; because we’ve built a routine for our life.

If time seems to fly by faster as we get older, maybe it’s because we have fewer temporal landmarks to frame the days into memorable sequences. We slip into a career, work Monday through Friday week after week, and entire years blend together into one block of our lives. I recently spent seven years working for one company, and the only thing about the job that made one year any different from the next were the big work trips and what happened outside of work that impacted the routine. New product releases, version upgrades, company meetings and even trade shows all blended together into a memory of what I did then versus what I do now. Where did the time go?

The thing is, in that same time period, I took memorable trips of a lifetime to faraway places, had significant milestone moments with family graduations and the passing of loved ones, and of course we all collectively had the pandemic, national elections, wars and a host of other memorable moments that locked time into amber. We don’t remember each day, we remember moments—and these moments are our temporal landmarks. Some are far more significant and far-reaching than others.

Where were you when the world stopped turnin’
That September day?
— Alan Jackson, Where Were You (When the World Stopped Turning)

A day like 9/11 is locked into memory, while the world turning in routine on the days leading up to it fade away. We’ll always remember where we were in that moment, just as we do other similar temporal landmarks. We tend to forget the flow of days around those landmarks. And while none of us wish for those kind of 9/11 landmarks to land in our lives ever again, we may use the theory to create more positive temporal landmarks for ourselves.

So how will today be remembered? What will stand out about this month in five years? How about next year—what temporal landmarks will we schedule into the next year of our lives to make the time really stand out as memorable? The time will flow into our past one way or the other. It’s up to us to make it something more than routine. A temporal landmark is something we’ll remember this time by. Maybe make it something more special than just taco Tuesday.
