Open Source Date Calculators for Business and Finance.
http://objectlabkit.sourceforge.net
It is available immediately for download via SourceForge or the Maven Central Repository (both Maven 1 and Maven 2). The homepage has some very quick examples.
The Kit provides Date Calculators and comes in two flavours:
- one based on pure JDK (1.5)
- one based on the Joda-time library (1.3+, jdk 1.5)
This library is now live in a major UK & international Bank (in their Credit Derivatives department). The library is small, lightweight and thread-safe.
The DateCalculator implementation is useful to any business; the other two interfaces are more specific to the financial industry.
The most common function of a lot of banking or business applications is the handling of holidays and weekends, a set of standard rules are implemented to deal with days falling on a holiday. The library does not attempt to guess the 'holidays', most business will have an official list anyway, but concentrate on the date manipulation and calculations.
What does it provide? Implementation of 3 interfaces
- DateCalculator for all date calculation and handling of weekends or holidays.
The supported algorithms are: Do Nothing, Move Forward, Move Backward, Modified Following and Modified Preceeding. The Calculators are immutable
once created but they can be easily composed to take into account multiple sets of holidays. The library also supports the calculation of generic tenor
dates (Spot, 1D, 1W, 2M, 3Y, etc)
- PeriodCountCalculator for calculating differences between two dates in days, months or years according to some financial algorithms: ACT/360, ACT/365, ACT/ACT, CONV/30-360, CONV/30-365_ISDA, CONV/30-360_ISMA
- IMMDateCalculator, to calculate the International Money Market dates (IMM Dates are 3rd Wednesday of March/June/Sept/Dec)
This kit is one of the first steps in pushing the Open Source movement up "the stack" towards business functionalities in the financial industry.
ObjectLab is not new to the open-source community having used numerous OS projects, participated in a few and sponsoring QALab (http://qalab.sourceforge.net), a tool that keep tracks over-time of the static analysis results from FindBugs, Checkstyle, PMD, Cobertura etc.
ObjectLab Kit is released under the business friendly Apache License.
We would like to thanks our friends and colleagues at XXXX for their help, reviews and suggestions.
Sorry for the long email...
Feel free to pass on to people who may be interested.
Enjoy!!
Benoit Xhenseval and Marcin Jekot
