How Many Weeks Is 6 Months?

6 months is about 26 weeks. Half a year is 182.5 days on average, which is 26.1 weeks. Six real calendar months are always between 181 and 184 days long, so the exact answer is 25 weeks and 6 days at the shortest and 26 weeks and 2 days at the longest.

6 months in weeks, days and hours

Unit	6 months equals
Weeks	about 26 (26.1 on average)
Days	about 182.5 (181 to 184 for real dates)
Hours	about 4,383
Fortnights	about 13

The average comes from dividing a year by two: a year is 365 days (365.25 on average, allowing for leap years), so half a year is about 182.5 days, or 26.1 weeks.

Why the answer is not always exactly 26 weeks

Months have different lengths, so six months starting in one month are not the same length as six months starting in another:

1 January to 1 July: 181 days in a normal year (25 weeks, 6 days), because February is short.
1 July to 1 January: 184 days (26 weeks, 2 days), because July, August, October and December all have 31 days.
In a leap year, any six months that include February gain one day.

Six calendar months are never fewer than 181 days or more than 184.

How to work it out yourself

Quick estimate: multiply 6 by 4.35. The answer is 26.1 weeks.
Exact answer for real dates: count the days from the start date to the same date six months later, then divide by 7.
Month-end dates: if the start date is the 29th, 30th or 31st and that day does not exist six months later, use the last day of the month. For example, 31 August plus six months is 28 February (29 in a leap year). Our method page explains this rule.

Common questions

Is 6 months exactly 26 weeks?

Not exactly. 26 weeks is 182 days, while six calendar months are 181 to 184 days. 26 weeks is a good everyday answer, but it can be a day or two short or long.

How many weeks old is a 6-month-old baby?

About 26 weeks. A baby turns six months old on the same date six months after birth, which is between 25 weeks 6 days and 26 weeks 2 days after the birth date. See halfway to one for ideas to mark the milestone.

Is 6 months pregnant the same as 26 weeks?

Not necessarily. Pregnancy is counted in weeks from the first day of the last menstrual period, and there is no single agreed way to turn those weeks into months. Ask your midwife or doctor which week applies to you.
