About AskTheDate

Fast, shareable answers to date and time questions.

AskTheDate is a collection of small, focused tools for the everyday date and time questions people actually search for: what day of the week a date falls on, how many days lie between two dates, what date is ninety days from today, how old someone is to the day, how many working days are in a stretch, and what time it is right now in any city. Alongside those it offers a world clock, an earnings calendar, and a newborn jaundice reference tool.

The URL is the UI

The idea that shapes the whole site is simple: every answer should live at its own address. Instead of filling in a form and clicking a button, you can read the answer straight from a URL — and you can bookmark it, share it, or link to it. A few examples:

  • /America/New_York/en/add-days/90/to/today
  • /Europe/London/en/days-between/today/and/2025-12-25
  • /Asia/Tokyo/en/day-of-week/2026-01-01

Because the parameters are in the path, the same link works for anyone, and the answer is computed fresh for the timezone it names.

How it works

Date math is handled with Day.js on top of the IANA timezone database, so results respect daylight-saving transitions and regional rules rather than assuming a fixed offset. The earnings calendar is built primarily from TradingView data, with Yahoo Finance as a fallback, and it refreshes roughly three times a day. The newborn jaundice reference ranges are drawn from the Bhutani hour-specific bilirubin nomogram (Pediatrics, 1999) and the American Academy of Pediatrics 2022 guideline on hyperbilirubinemia — it is a reference, not medical advice.

Languages and timezones

The interface is available in six languages — English, Spanish, French, German, Chinese, and Japanese — and the tools cover 72 timezones, so a question asked from Tokyo and the same question asked from São Paulo each get the right local answer.

Who runs it

AskTheDate is built and maintained by Dante, an independent developer. It is a small, self-funded project kept free through advertising. If you spot a bug, a wrong result, or something that could be clearer, that feedback genuinely helps — reach out through the contact page.
