What the Add Hours from Now Calculator Does Not Do
It is just as useful to know a tool's limits as its abilities. The {fk} will not interpret your situation, factor in your personal context, or make the decision for you. It performs one calculation, reliably, and leaves the judgement calls to you. That division of labour is deliberate: the arithmetic is where tools shine, and context is where humans do. Use it for the numbers, and bring your own sense of the bigger picture — or a professional when the stakes are high.
What the tool absolutely will not do is invent data. If an input is missing or out of range, it tells you rather than guessing. You always know exactly what went into the answer, which is more than most quick calculations can claim.
