Frequently asked questions
- Can the tip calculator split unevenly?
- It splits the total evenly across the headcount you enter. For an uneven split, divide each person's share of the bill first, then apply the same tip percentage.
- Does the date calculator count both endpoints?
- It counts the gap between dates, so the same date is 0 days and consecutive days are 1. Add 1 if you need both the start and end counted.
- Are these calculators free with no ads in the way?
- Yes. Every tool is free, runs in your browser, and puts the calculator first — no pop-ups, no signup, and nothing that buries the answer.
