Everyday Calculators
Eight tools for the small sums that come up in daily life: how old you are, what the bill splits to, what the trip costs, how long until the deadline. None of them needs a sign-up, and each one gives you the answer in seconds.
- Age Calculator — exact age in years, months, and days, plus next birthday and age difference.
- Tip Calculator — tip, tax, total, and each person’s share, before or after tax.
- Fuel Cost Calculator — what a trip will cost in fuel, round trip and per passenger.
- Days Between Dates Calculator — days between any two dates, inclusive or exclusive, with both weekdays.
- Date Calculator — add or subtract days, weeks, or months from any date.
- Time Duration Calculator — hours between two times, including overnight spans and two-block shifts.
- Speed Calculator — average speed in mph or km/h, plus running pace.
- Cooking Converter — cups, tablespoons, ml, and grams, with ingredient weights for baking.
The date tools work as a set: days-between counts a gap, the date calculator lands on a new date, and the time-duration calculator handles the hours inside a day. For a road trip, run the fuel-cost calculator for the money and the speed calculator for the timing, and you have the whole trip planned.
