The answer in detail

Thursday, January 1, 2026 falls on a Thursday. It is day 1 of 365 in 2026, in ISO week 1, in quarter 1 and in winter in the northern hemisphere. The date is 278 days ago, and it is a weekday, so offices and schools are normally open. It coincides with New Year that year.

The moon and the calendar

On January 1, 2026 the moon is a Waxing Gibbous with about 93% of its disc lit, roughly 12.4 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.
