"Is 2028 a leap year?" Yes — and unlike 2026, it is. February 2028 has 29 days, the year has 366 days, and anyone born on February 29 finally gets a real birthday for the first time since 2024. Leap years come around every four years, and 2028 is the next one on the calendar after 2024.

Here's why 2028 qualifies and how to confirm it yourself.

Why 2028 Is a Leap Year

The leap-year test for 2028 is straightforward:

  • Divisible by 4? 2028 ÷ 4 = 507. Yes.
  • Divisible by 100? No. (2028 isn't a century year.)
  • That's it — 2028 is a leap year. The century exception doesn't apply because 2028 isn't a century year.

The full Gregorian rule has a third clause for century years, but you only need it for years like 2100 or 2400. For ordinary years like 2028, the divisible-by-4 check is the whole story.

What Changes in a Leap Year

The extra day on February 29 ripples through the calendar:

  • Year length: 366 days instead of 365.
  • Weekday shifts: Dates after February 29 jump forward by two weekdays from the prior year (instead of the usual one). So if March 1 was a Sunday in 2027, it'll be a Tuesday in 2028.
  • Day-of-year numbers: March 1 is day 61 in a leap year (60 in a standard year). December 31 is day 366.
  • Annual totals: Payroll, billing, and per-day calculations use 366 days. A daily subscription billed annually earns one extra day of revenue.

The Century Exception: Why 2100 Won't Be Leap

The one leap-year subtlety worth knowing is the century rule. A year divisible by 100 is NOT a leap year unless also divisible by 400. So 2100 — divisible by 100 but not 400 — will be a standard 365-day year, breaking the four-year pattern. The last time this happened was 1900; the next will be 2100. The year 2000 was a leap year because 400 divides it. 2028 has no such complication.

Check Any Year Yourself

Our Leap Year Checker applies the full Gregorian rule to any year. Enter 2028 and it confirms: yes, leap year, 366 days, February has 29. Try 2026 (no), 2100 (no, century exception), and 2000 (yes, divisible by 400) to see the rule in action.
