Time Between Days Calculator

This calculator is useful for determining the number of days, weeks, months, and years between two dates. It helps users track durations for projects, events, or personal milestones.

Calculation Formula

The difference between two dates is calculated by subtracting the start date from the end date, resulting in the total time in milliseconds. From there, the days, weeks, months, and years are derived using the following formulas:

\[ \text{Days Between} = \frac{\text{Difference in Milliseconds}}{1000 \times 3600 \times 24} \]

\[ \text{Weeks Between} = \frac{\text{Days Between}}{7} \]

\[ \text{Months Between} = \frac{\text{Days Between}}{30} \]

\[ \text{Years Between} = \frac{\text{Days Between}}{365} \]
