Why Calculate Age in Weeks?
We typically think of age in years. But weeks tell a more detailed story.

📅 Detailed Age Tracking
Knowing your age in weeks offers a more granular perspective. While someone might be “29 years old,” they’re also approximately 1,508 weeks old. That hits differently — and adds a fun, insightful twist to birthdays.
👶 Baby Development
In early life, babies develop week by week. Milestones like rolling over, smiling, or sitting up are tracked weekly by pediatricians and parents alike. This tool simplifies that process.
