What Timezone Converter actually does
Timezone Converter takes the inputs you provide, plugs them into a well-known formula, and returns the result in human-readable units. The formula isn't proprietary — it's the same one your doctor / accountant / professor uses, just with the arithmetic outsourced to your browser.
The math in plain English
The underlying formula expresses a relationship between the inputs you provide and the output you want. The version Timezone Converter runs is the standard, accepted formula used everywhere — there is no proprietary "Favtoo math." That matters because it means the number you get matches what any other reputable calculator (or your doctor's spreadsheet) would produce for the same inputs.
When to trust Timezone Converter, when to double-check
Timezone Converter is correct for what it computes. The harder question is whether the formula is the right tool for your situation. A calculation from Timezone Converter is a useful data point, not the final word — especially for anything that affects a decision with real consequences.
