About GlobalTimeTools

GlobalTimeTools.com is an independent website offering free online calculators and converters for time zones, dates, currencies, loans, investments, Indian taxation and live market data. It is built and maintained by Karthick Subramaniam, co-founder and COO of eAuditor Office Private Limited, a professional services firm in Coimbatore, India that works daily with the tax, payroll and compliance calculations these tools automate.

Why this site exists

Most calculation websites are either cluttered beyond use or quietly wrong: outdated tax slabs, simple interest passed off as compound, exchange rates with hidden margins. We built the tools we wanted to use ourselves: current rules with the assessment year labelled, formulas shown next to every result so you can verify the working, and pages that load fast on an average phone connection.

Our principles

Accuracy first. Tax tools state their financial year and are updated when rules change. Formulas follow the same conventions banks, exchanges and tax software use.

Privacy by default. Calculators run in your browser. Salaries, invoices, passwords and text you enter are never uploaded to our servers. Live market and currency data is fetched from public sources; your inputs are not part of those requests.

Free means free. No sign-up, no paywall, no locked features. The site is supported by advertising, clearly separated from content.

Data sources

Currency rates come from the European Central Bank’s daily reference rates. Market prices come from public market data feeds and may be delayed up to 15 minutes; they are provided for information, not as investment advice. Time zone data comes from the IANA time zone database via your browser.

Corrections

If you find an error in any calculation, tell us through the contact page. Accuracy reports get priority and are typically fixed within days.
