Why this category?

Porquê utilizar as ferramentas datas e tempo?

A date is not just a number: months have different lengths, leap years matter, and timestamp formats quickly make manual calculations tedious. This category groups tools whose main purpose involves a date, a duration, or a representation of time.

Available tools already cover ages, date differences, and timestamps. The family is designed to grow into business-day calculations, adding or subtracting days, calendars, week numbers, time zones, and other time conversions without scattering them across Mathematics or Development.

Use cases

Compare two dates

Measure the exact difference between two dates or deadlines.

Calculate a duration

Get an age, interval, or duration expressed in several units.

Convert a timestamp
