Date Functions

Aspen Graphics 4.0 introduces the following date functions:

• AddDays()

• AddMonths()

• AddYears()

• AddBusDays()

• BusDays()

• FirstOfMonth()

• LastOfMonth()

These date functions have been included to support Natural Gas Swaps, which require weighting by the number of days traded vs. the number of business days in a month. There are a host of useful applications for these formulas.
