A different way to see a lifetime
You have about 960 months. 1200 if you’re healthy. 1440 if you’re lucky.

Your life calendar
One square. One month. All 1,440 months of a 120-year span, in six stages of 20 years. Each square is filled in as a month passes.

Where you are
How the months break down
Every ten years, how many months are behind you and how many are ahead.
Not all months are equal
Health, energy, responsibilities and relationships change. Months remaining does not mean the same circumstances for all of them.
It’s not just months. It’s moments.
A lifetime of experiences is a surprisingly small number of moments. Change a number to match your own life.
Three clocks running together
Lifespan
How long am I alive?
Healthspan
How long am I healthy and able to do what I value?
Time with someone
How much overlapping time remains with a person who matters?
A common mathematical mistake
At age 60, don’t assume 960 − 720 = 240 months left. That’s not how life expectancy works. Life expectancy at birth is a population statistic, not a personal timer. The longer you live, the longer your expected remaining life becomes, which is called conditional life expectancy. For example, US figures from the CDC put life expectancy at birth near 79 years (2024), and the average remaining life at age 65 near 19.5 years, about 234 months (2023).
So the 960-month idea is philosophical, not a personal expiration date.
But there’s another side
A finite resource gains value. A song ends. A sunset fades. A season passes. That limitation is part of what makes them precious.
This month
Your months are yours to use
You cannot add months to your life, but you can add life to your months.
Two people may both reach 960 months. One merely passed time. The other inhabited it.
You don’t experience life in years. You experience it in months.
