Introduction
While the year 2026 is an even-numbered year, dividing the number of the year in two (2) yields an odd number and, more specifically, an odd prime, namely the number 1013. However, the previous year, 2025, was a perfect square with only two (2) distinct prime factors while the next year, 2027, will be a prime number by itself.
Prime Factorization
Though this year is an even-numbered year, 2026 is yielded by the numbers 2 and 1013, in the proper prime factorization. Last year, 2025, was a perfect square based on the number 45, which itself contains a perfect square within the prime factorization of the number. The number 45 is yielded by the numbers nine (9) (three squared), and five (5). As previously noted, next year, 2027, will be a prime-numbered year, thus making the year entirely indivisible.
Calendar
Since the year 2026 is not divisible by any of the numbers four (4), one hundred (100), or four hundred (400), the calendar is an identifiable common year calendar, thus spanning three-hundred-sixty-five (365) days. Like the years 2015 or 2037, the year 2026 is notable for beginning on a Thursday and ending on a Thursday exactly fifty-two weeks later.
Please keep in mind that the dates of holidays calculated astronomically, rather than mathematically, i.e. Easter, may not align perfectly with calendars of years with similar days of the week.
Weekday Reference
The months of the current year, 2026, begin on the following weekdays:
- January: Thursday
- February: Sunday
- March: Sunday
- April: Wednesday
- May: Friday
- June: Monday
- July: Wednesday
- August: Saturday
- September: Tuesday
- October: Thursday
- November: Sunday
- December: Tuesday
Since 2026 is a common year, the month of January must begin on the same day of the week as October, and the month of February must begin on the same day of the week as March and November. As always, April and July must begin on the same weekday, and September and December must as well.
Also, as a common year, the months of May, June, and August begin on distinct days of the week, clearly separate from the days of the week associated with any other month of the year. Interestingly, May uniquely never begins nor ends on the same day of the week as any other month of the year, ever.
