Estimate model
The page calculates elapsed days from birth, groups them into weeks and builds the target birthday from the age you select.

ASSUMPTIONS & INTERPRETATION
Life in Weeks
Visualise elapsed life as seven-day blocks and compare weeks already lived with a target age that you choose yourself.
What the number means
Filled blocks represent elapsed weeks; remaining blocks are only the distance to your chosen reference age. They are not a forecast of lifespan.
Worked example
10,000 elapsed days contain 1,428 full weeks and four extra days, which is why week counts should not be approximated as age × 52.
