October 18, 2026 falls on a Sunday
October 18, 2026 is a Sunday. It is 25 days from today, September 23, 2026. The date is day 291 of 365 in 2026, it sits in ISO week 42, and it is the 18th of a 31-day month with 13 days after it.
What day of the week is October 18?
In 2026 it is a Sunday. The weekday is not a property of the date itself, it is a property of the date in a given year, so the honest answer always names the year. A common year is 365 days, which is 52 weeks plus one spare day, so a fixed date moves forward one weekday from one year to the next. A leap year inserts a second spare day, so the step is two whenever 29 February falls inside the gap. That is why October 18 works its way around the week rather than repeating on a tidy schedule.
