To understand how many months are in 18 weeks, it’s helpful to know that months and weeks don’t always have a simple, even conversion because they have different numbers of days.
On average, a month has about 4.33 weeks. So, if you divide 18 weeks by 4.33, you get a little more than 4 full months. This means that 18 weeks is roughly 4 months and a few extra days.
