Frequently you find yourself performing date calculations such as:

• How many days do I have to buy my spouse a birthday present?
• If a contract expires in 15 weeks, what is the expiration date?
• How old will I be when I finish paying my loan?
• How many seconds, minutes, hours, days, weeks, months or years have elapsed since that important event?

The following operations are supported:

• Subtracting two dates.
• Adding a date value (days, weeks, months or years) to a date.
• Adding a time value (seconds, minutes, and or hours) to a date or time.
• Converting integral values to date or time units to aid in performing date and time calculations.
• Performing basic arithmetic calculations on integral numbers (add, subtract, multiply and divide).
• Storing and manipulating values in the calculator's memory.
