Inputs

How to use

  1. Pick a date for "Start date".
  2. Read the result: 6 months from the start date, date, day of the week, and days moved. It appears once every required field has a valid value.

Worked examples

Example 1. Inputs:

  • Start date: October 8, 2026

Results:

  • 6 months from the start date: Thursday, April 8, 2027
  • Date: April 8, 2027
  • Day of the week: Thursday
  • Days moved: 182

How this is worked out: Oct + 6 months = Apr of the next year, day 8 kept. Days crossed: 31 (Oct) + 30 (Nov) + 31 (Dec) + 31 (Jan) + 28 (Feb 2027) + 31 (Mar) = 182 = exactly 26 weeks. Oct 8, 2026 is a Thursday, so the result is a Thursday.

Example 2. Inputs:

  • Start date: August 31, 2026

Results:

  • 6 months from the start date: Sunday, February 28, 2027
  • Date: February 28, 2027
  • Day of the week: Sunday
  • Days moved: 181

How this is worked out: Aug + 6 = Feb 2027. Feb 31 does not exist (2027 is not a leap year), so the day is clamped to Feb 28. Adding by raw days or JS setMonth would roll into March. Days: 30 (Sep) + 31 (Oct) + 30 (Nov) + 31 (Dec) + 31 (Jan) + 28 (Feb) = 181. Jan 1, 2027 is a Friday; Feb 28 is 58 days later (8 weeks and 2 days), so a Sunday.

Example 3. Inputs:

  • Start date: August 31, 2023

Results:

  • 6 months from the start date: Thursday, February 29, 2024
  • Date: February 29, 2024
  • Day of the week: Thursday
  • Days moved: 182

How this is worked out: Aug + 6 = Feb 2024, a leap year, so the clamp gives Feb 29, which was a Thursday. Days: 30 + 31 + 30 + 31 + 31 + 29 = 182.

Example 4. Inputs:

  • Start date: December 31, 2026

Results:

  • 6 months from the start date: Wednesday, June 30, 2027
  • Date: June 30, 2027
  • Day of the week: Wednesday
  • Days moved: 181

How this is worked out: Dec + 6 = Jun 2027. June has 30 days, so Dec 31 clamps to Jun 30. Days: 31 (Jan) + 28 (Feb) + 31 (Mar) + 30 (Apr) + 31 (May) + 30 (Jun) = 181. Jan 1, 2027 is a Friday; Jun 30 is 180 days later (25 weeks and 5 days), so a Wednesday.

Where this comes from

Add a length of time to a date. Years and months are added first, keeping the day of the month or the last day of a shorter month. Weeks and days are then added as whole days. Source: The Gregorian calendar: month lengths and the leap year rule (every fourth year, except century years not divisible by 400).

Limitations

  • Uses the calendar as it is today (Gregorian), including leap years, for every date.
  • The start date comes from your device's date when the page opens.

FAQs

Q: Does it start counting from today?
A: Yes by default. The start date is filled with today's date when the page opens, and you can change it to any other date.
Q: Is the start day counted?
A: No. The start day is day zero, so the result is exactly the stated amount of time after it.
Q: What day of the week is the result?
A: The weekday of the resulting date is shown beside it.
Q: What happens when the month it lands in is shorter?
A: When months or years are added and the resulting month has no such day, the last day of that month is used. One month after January 31 is the last day of February.
