Everyday tools for plans, measurements, and choices
Count calendar days, calculate clock durations and pace, convert measurements, or pick a random entry.
A small planning question often needs a clear convention more than a complicated application. Decide whether a date range is inclusive, whether a clock time ends on the next day, or which gallon a source means. The tools keep those choices visible so a result is easier to understand and check.

Keep a date separate from an instant
A calendar day and an exact timestamp contain different information. The simple date and clock tools do not model local daylight-saving transitions or rules for working days.
Choose and label your measurement
A mile is not a kilometre, and US and imperial gallons are different. Select the original unit explicitly instead of relying on an unlabeled number in another source.
Put the tools in context.
All guidesDates, clock times, and timestamps are different inputs
Choose calendar-day counting, clock duration, or a UTC timestamp according to the question you actually need to answer.
A ratio, a fraction, and a percentage walk into a plan
Tell part-to-part and part-to-whole comparisons apart before scaling a simple quantity.
