One of the most common queries on Wolfram|Alpha is a user entering his or her date of birth to see how many years, months, and days old he or she is today.

Since this feature first became popular, we added more birthday-specific features for this query type. By adding “birthday” to your query, you’ll get even more detailed information, such as a birthday countdown, a notable dates pod, and astrological birth information.

For example, submit a query such as “birthday March 29, 1990” to see how many days there are until your next birthday (time to start planning, March 29ers!) and how long it’s been since your last birthday.

Birthday March 29, 1990

Scroll down a bit further to the “Notable dates” pod and click the “More” button in the right-hand corner to unlock dozens of other excuses to celebrate, such as your pi or Martian birthday. This is just a sample of many notable dates you’ll find:

Wondering what was happening in the cosmos on the day you were born? You can discover where the Sun, Moon, and planets were located on your special day. (We won’t even attempt to make predictions on what their placement means for you. We’ll leave that up to the astrologists!)

Astrological birth information? Seriously?
You could as well add the number of eggs the world population ate on this day. This would be as useful.
That’s kind of sad.

A big fan of Wolfram|Alpha

It may sound stupid, but I wanted to calculate the number of points (or the number of pixels) in an A4 page of fax quality.
I tried that in various ways but nothing useful came up.
So this is my suggestion for improvements. :)

Thank you.

(Sorry, I missed the “related to your birthday”.)

Hello your feedback button does not work which is not actually my feedback. Wolfram Alpha failed to balance the chemical equation C5H10N2O3+O2->H2O+CO2+NH3. This equation can be balanced with the coefficients 1, 9/2, 2, 5, 2 respectively.
