Instructions
To calculate the number of days between any two dates such as in computing in-custody credits (i.e. the left-hand calculator above):
- Step 1 - Choose your starting date.
- Select the starting date of your choice using the drop-down arrows next to each selection box. When you open the Day Calculator, the date is automatically set to today's date. As the calculator takes today's date from your system clock, it is important to make sure that your system date is correctly set for this function to work properly.
- Step 2 - Choose your ending date.
- Select the ending date of your choice using the drop-down arrows next to each selection box. When you open the Day Calculator, the date is automatically set to today's date. As the calculator takes today's date from your system clock, it is important to make sure that your system date is correctly set for this function to work properly.
- Step 3 - Calculate.
- Press the button marked "Calculate" to carry out the calculation. The number of days difference will be displayed at the bottom of the form. Note that the calculation includes the starting date itself (i.e. day number 1 is the day you enter as your starting date) AND includes the ending date (i.e. the day you enter as your ending date).
To add or subtract a chosen number of days to or from any date as in computing some due dates (i.e. the right-hand calculator above):
- Step 1 - Choose your starting date.
- Select the starting date of your choice using the drop-down arrows next to each selection box. When you open the Day Calculator, the date is automatically set to today's date. As the calculator takes today's date from your system clock, it is important to make sure that your system date is correctly set for this function to work properly.
- Step 2 - Choose whether to add or subtract.
- Either select the radio button marked "Add" or the radio button marked "Subtract".
- Step 3 - Type in the number of days to add or subtract.
- This must be a whole number.
- Step 4 - Calculate.
- Press the button marked "Calculate" to carry out the calculation. The new ending date will be displayed at the bottom of the form, including the day of the week. Note that the calculation excludes the starting date itself (ie. day number 1 is the day after your starting date) but includes the ending date.
