6 Month Calculator: Date 6 Months From Today | CalcNova
Find the exact date 6 months from today or from any start date, see the weekday, how many days and weeks that is, and compare it with 180 days. You can also change the number of months or count backwards.
6 month calculator
Dates use the calendar, so months of different lengths and leap years are handled for you.
How it works
The calculator keeps the day of the month, adds (or subtracts) the number of months, and rolls the year over when it passes December or January. If the day does not exist in the new month, the result becomes the last day of that month. The day count is the exact number of calendar days between the two dates, and weeks are shown as whole weeks plus remaining days.
Worked example
Start date: 24 October 2026. Six months later is Saturday, 24 April 2027. That is 182 days, or exactly 26 weeks, and 130 weekdays. Counting 180 days instead gives Thursday, 22 April 2027, two days earlier. Going back six months from the same start gives 24 April 2026.
Month-end dates
| Start date | + 6 months | Why |
|---|---|---|
| 31 August 2026 | 28 February 2027 | February 2027 has 28 days |
| 31 August 2027 | 29 February 2028 | 2028 is a leap year |
| 31 December 2026 | 30 June 2027 | June has 30 days |
| 30 January 2026 | 30 July 2026 | The 30th exists in July, so nothing changes |
6 months versus 180 days
Six calendar months always fall between 181 and 184 days. For example, 31 December to 30 June is 181 days, while 1 July to 1 January is 184 days. If a document says "6 months", count calendar months. If it says "180 days", count days. The two dates can differ.
When people use a 6 month date
- Probation periods and fixed-term contract reviews
- Rental or lease reviews and notice periods
- Product warranties and service intervals
- Follow-up appointments and check-ups
- Savings goals, project milestones and anniversaries
The rules for these differ between employers, landlords and countries, so check the wording that applies to you.
Frequently asked questions
- How do you add 6 months to a date?
- Keep the day of the month, move the month forward by six, and roll into the next year if needed. For example, 24 October 2026 plus 6 months is 24 April 2027. If the day does not exist in the target month, the result moves back to that month's last day.
- Is 6 months the same as 180 days?
- Usually not. Six calendar months span 181 to 184 days depending on the start date, so a deadline written in days and one written in months can differ by up to four days. The calculator shows the 180-day date next to the 6-month date so you can compare.
- What happens if I start on the 31st?
- Months with fewer days do not have a 31st, so the result lands on the last day of the month. 31 August 2026 plus 6 months is 28 February 2027, and 31 August 2027 plus 6 months is 29 February 2028 (a leap year).
- Does the weekday count include public holidays?
- No. The weekday count covers Monday to Friday only and ignores public holidays, which differ by country and region. It counts days after the start date up to and including the result date.
- Can I count backwards or use another number of months?
- Yes. Choose Before the start date to go backwards, and type any whole number of months from 0 to 1200.
- Can I rely on this for a contract or legal deadline?
- Use it as a quick check. Contracts and laws can define months, business days and cut-off times in their own way, so confirm the rule that applies to your document.
