Date Calculations
Date calculations involve determining the time span between two dates. This can be measured in days, weeks, or months.
- 1 week = 7 days
- 1 month ≈ 30.44 days (average)
- 1 year = 365 days (366 in leap years)
Date Formulas
Here are the key formulas for date calculations:
- Total Days = End Date - Start Date
- Weeks = Total Days ÷ 7
- Months = (End Year - Start Year) × 12 + (End Month - Start Month)
Practical Examples
Example 1 Basic Date Difference
Calculate the number of days between January 1, 2024 and January 10, 2024.
Total Days = 10 - 1 = 9 days
Example 2 Month Calculation
Calculate the number of months between January 1, 2024 and March 1, 2024.
Months = (2024 - 2024) × 12 + (3 - 1) = 2 months
Example 3 Complex Date Calculation
Calculate the time span between January 1, 2023 and March 15, 2024.
Total Days = 440 days
Weeks = 440 ÷ 7 ≈ 62.86 weeks
Months = (2024 - 2023) × 12 + (3 - 1) = 14 months
