When calculating a child's age, what is your month equivalent in weeks? If a child is 44 weeks old, is he 11 months old?

When calculating a child's age, the developers recommend calculating in months and days, rather than weeks. Because all months except for February are longer than 4 weeks, using 4 weeks to represent a month increases a child's age artificially. For easy age calculation, you can use our [website calculator](/content/free-resources/asq-calculator/index.html) or the free ASQ Calculator app available in the Apple and Google Play app stores.
