I work in a court reporting firm. We have very strict date deadlines for read and sign deponents. This calculator is awesome. I can put in the delivery date and calculate 30 days from the delivery date and have a very definite due date for our system. I love this!

This is really awesome! And super fast. *Suggestion* I think it would be even better if somehow we could set a reminder for the particular date through this website itself, maybe through email or something. I dont know if this is already present here and I am not aware of it. I think that feature would enhance this website even more.
