press enter to put a year into the calculator. the calculator will give a rough estimate of how many days ago that year was. just remember it is not always accurate because the math is difficult. Which is why I added a make me smarter button which gives you ways to make the calculator better at making calculations.
I just wanted to make some interesting applications on scratch. (btw the calculator pretends every day is in december 31st because it doesn't calculate the month, week and day and it only calculates the year so that's why the calculator is off sometimes.
