The answer in detail

Thursday, October 1, 2026 falls on a Thursday. It is day 274 of 365 in 2026, in ISO week 40, in quarter 4 and in autumn in the northern hemisphere. The date is 5 days ago, and it is a weekday, so offices and schools are normally open. It does not coincide with any of the major holidays tracked on this site that year.

The moon and the calendar

On October 1, 2026 the moon is a Waning Gibbous with about 69% of its disc lit, roughly 20.4 days after the previous new moon. That figure is computed from lunar phase formulas, not looked up, so it is available for any year in the range.

How weekday lookups work

The weekday of a date is found by counting the days from a known reference date and taking the remainder after dividing by seven. The calculator applies that rule to real Gregorian dates, including leap days, which is why it works equally well for a birth date in 1985 and a wedding date in 2032.
