The Family Chain
Enter three names and three birth years — you, a parent, and a grandparent. The Family Chain calculates how much life the three of you have shared so far, then estimates how much simultaneous time may still be left.
“The family line does not move in neat decades. For a while, three generations are all
alive inside the same ordinary year.”
Waiting for your names
The window appears here.
The Family Chain returns four cards: your shared years with a grandparent, your shared years with a parent, the years all three generations overlapped, and the estimated time still left while all three may be alive together.
You and your grandparent
The years the oldest link in the chain has overlapped with your own life.
You and your parent
The simpler overlap — still part of the same emotional measure.
All three of you
One number for the years three generations stood inside the same world.
The window
The remaining estimate for how long that three-generation moment might hold.
