How 6 months converts to days
Every time conversion goes through the second, which is the SI base unit for time. 6 months is 15,778,476 seconds, and dividing that by the length of one day gives the answer.
1 month = 30.44 days 6 × 30.44 = 182.6
Written as a clock reading rather than a decimal, that is 182 days 14 hours 54 minutes 36 seconds. The decimal form is what a form field or a spreadsheet wants; the clock form is what a schedule wants, and the two are not interchangeable.
Where 6 months shows up
Half a year averages 182.6 days, but the two real halves of a year are lopsided: January through June is 181 days in a common year while July through December is 184. That three-day spread is why a six-month rule and a 180-day rule are not the same rule, and why anything with a hard half-year boundary, a validity requirement or a reporting window, should be counted on the calendar. /date/date-difference-calculator does that from actual dates.

Frequently asked questions
How many days is 6 months?
6 months = 182.6 days. 1 month = 30.44 days, so the conversion is 6 × 30.44 = 182.6. Because the calculation involves a month or a year, it uses the Gregorian average rather than a real calendar span, so treat it as an estimate.
How long is 6 months on a clock?
182 days 14 hours 54 minutes 36 seconds. That is the same span written out in whole units instead of a decimal, which is usually what you want when you are setting a timer or reading a schedule rather than filling in a form.
Why is this an estimate rather than an exact answer?
Months are 28 to 31 days and years are 365 or 366, so neither has a single fixed length. This page uses the Gregorian average — 365.2425 days a year, which is a twelfth of that, or 30.436875 days, a month. For a span between two real calendar dates, use the date difference calculator instead; it counts the actual days.
What is 6 months in practice?
Half a year averages 182.6 days, but the two real halves of a year are lopsided: January through June is 181 days in a common year while July through December is 184. That three-day spread is why a six-month rule and a 180-day rule are not the same rule, and why anything with a hard half-year boundary, a validity requirement or a reporting window, should be counted on the calendar. /date/date-difference-calculator does that from actual dates.
