Calculating a time span between two days is a common concern in many areas such as planning, time management and even science. The time span can be expressed in different units such as minutes, hours, days or months.

Here is a simple guide to calculating these time spans:

## Minutes and hours

**Determine the exact times**: Write down the exact times of the two days between which you want to calculate the time span.**Calculate in hours**: Subtract the start time from the end time in hours. If the end date is later than the start date, note the number of days in between and multiply by 24 (hours per day).**Calculation in minutes**: Multiply the number of hours by 60 to get the time span in minutes.

## Days

- Calculation
**of days**: Simply subtract the start date from the end date to get the number of days in between. Many calendar apps or online calculators also offer this function.

## Months

**Calculating**months: Calculating months can be more complex as months have different lengths. A simple way is to use specialized tools or software that calculates the exact number of months between two dates.

## Points to note

**Time zones**: If the two dates are in different time zones, you should take this into account in your calculation.**Leap years**: When calculating over longer periods that include leap years, you need to take the extra days into account.

Calculating time spans is a useful tool in many different contexts. With a clear methodology and the support of specialized tools where appropriate, this can be done easily and accurately.
