To calculate how many days are in 3 years, you need to consider whether those years include leap years or not.

Basic Calculation (Non-Leap Years)

• 1 year = 365 days
• 3 years = 3 × 365 = 1,095 days

Including Leap Years

A leap year has 366 days. Leap years occur every 4 years, except for years divisible by 100 but not by 400.

• If there is 1 leap year in the 3-year period:
  • 2 regular years = 2 × 365 = 730 days
  • 1 leap year = 366 days
  • Total = 730 + 366 = 1,096 days

Summary

Scenario| Number of Days
---|---
3 regular years| 1,095 days
3 years with 1 leap year| 1,096 days
