The answer depends on today's date. The calculator reads today's date automatically and adds exactly 6 calendar months. For example, if today is January 15, six months from today is July 15. Use the calculator above with the default settings to get the precise date.
If today is June 26, adding 6 months lands on December 26. Simply count forward six calendar months: June → July → August → September → October → November → December 26.
Starting from December 1, adding 6 months gives you June 1 of the following year. The calculation crosses the year boundary, moving from December through January, February, March, April, May, and landing on June 1.
Six months is approximately 182–184 days, depending on which months are included. The exact number varies because months have different lengths (28–31 days). The calculator shows the precise day count for your specific date range.
To find the date 6 months in the past, select '(–) Subtract 6 Months' from the Add or Subtract dropdown, then set your start date to today. The calculator will return the exact date that was 6 months ago.
Some month additions can result in an invalid date — for example, August 31 plus 6 months would be February 31, which doesn't exist. In those cases, the calculator automatically adjusts to the last valid day of that month, which would be February 28 (or 29 in a leap year).
Yes. The calculator uses JavaScript's native Date object, which correctly handles leap years. If your 6-month span includes February in a leap year, the extra day is automatically accounted for in the total days count.
They are not the same. Adding 6 calendar months moves the month value forward by 6 while keeping the same day of month. Adding 180 days counts exactly 180 individual days. Depending on the months involved, the resulting dates can differ by several days.
