Monday, May 3, 2027 falls on a Monday. It is day 123 of 365 in 2027, in ISO week 18, in quarter 2 and in spring in the northern hemisphere. The date is 213 days from today, 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.
May 3 in other years
May 3 falls on these weekdays over the next five years: 2028: Wednesday, 2029: Thursday, 2030: Friday, 2031: Saturday, 2032: Monday. Looking back, it fell on: 2026: Sunday, 2025: Saturday. The weekday moves forward by one each year, and by two after a leap day, which is why anniversaries and birthdays shift through the week.
The moon and the calendar
On May 3, 2027 the moon is a Waning Crescent with about 10% of its disc lit, roughly 26.5 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.

Today's date at a glance
Today is Friday, October 2, 2026. That is day 275 of 365 in 2026, in ISO week 40, with 90 days to go before the year ends. The next dates people plan around are Diwali on Saturday, October 10; Columbus Day on Monday, October 12; Halloween on Saturday, October 31. The moon is a Waning Gibbous tonight, with about 66% of its face lit. All of these figures are recalculated when the page loads, so they always describe the day you open it, not the day the page was published.
How the calendar works
The Gregorian calendar has twelve months of 28 to 31 days. A normal year has 365 days and a leap year has 366, with the extra day added to February in every year divisible by four except century years that are not divisible by 400. Because 365 is one more than 52 weeks, most dates move forward one weekday each year and two after a leap day. Weeks are numbered under ISO 8601, which starts weeks on Monday and gives week 1 to the week containing the first Thursday of January.
