Daily Life: Calculators and Tools
Dates, deadlines, age and averages for everyday calculations.
How many days are left until the deadline? What will the date be in ninety days? What grade do I need on the last test to reach my average? These are common questions, but they tend to start arguments because nobody wants to count month by month on their fingers.
The calculators in this category answer these questions precisely and explain the rules hidden behind the calculation, such as leap years, months of different lengths and weights on grades.
