Hi,
This work is purely based on core Java. Time calculations are the trickiest thing in the Java, but now, it has become very easy in the new release.
I can take up your work and get it done as per your requirement.
Rahu kalam, yemma kandam, nalla neram can be calculated for any day and any location provided we have the formula correct.I can work on this.
Please let me know your wish!
