Age Calculator and Life Visualization

Posted In: Counting

This is a simple age calculator that calculates your age down to the second.

The age calculator should be relatively self-explanatory, just enter your birthdate into the tool.  You can also enter the time of birth (if you want to), otherwise it will assume you were born at midnight.



There are two options for viewing your “age”.

  • The first (“Numerical Age“) is a table that shows the number of years, months, days, hours, minutes and seconds since you were born. It also shows how long it will be until your next birthday.  You can also use the Start Clock button to see your age change each second.
  • The second (“Graphical age“) is a figure that shows your age in the context of a 90 year lifespan.  Each block shown is one week and there are 52 weeks (blocks) in a year (row) and 10 years (rows) per decade (group of blocks).

This visualization is based on the the very interesting Wait But Why post “Your Life in Weeks” by Tim Urban.  It’s a bit humbling to see your life laid out in this way, and to think about how you will spend the (hopefully many) remaining weeks of your life.

You can click the URL button to create a URL that is based on the your birthday (so you don’t have to type it in again).  Just copy the URL in the address bar at the top of your browser (after pressing the button) to share with others.

Programming: this program was written in javascript and uses the moment.js library to simplify the date calculations.

Financial Freedom Calculator (Multi-Period FIRE Visualization)

Posted In: Financial Independence

This is an update to the Financial Freedom Calculator. That one still works well, but this version adds the ability to add multiple savings amounts representing different periods in time. This allows you to visualize your progress towards financial freedom rather than just giving you the latest value for your freedom date. It does so by showing different colors for the different periods (you specify them by adding different savings amounts and names). It should be fairly obvious looking at the calculator, but if you had a total of 25000 in savings in 2016 and 70000 in 2017, then your calculator is colored in two sections representing the freedom days you had achieved in the two different years.

Financial Freedom Calculator

Posted In: Financial Independence

The goal of the freedom calculator is to let you know how close to financial independence (i.e. freedom) you are, measuring your progress in terms of freedom days.  The key determinants for retirement are total retirement savings and annual spending.

Freedom days refers to the number of days that your retirement savings could sustain you (without working) each year (indefinitely) at your current spending level. Once you reach 365 freedom days per year, you’ve got enough money saved up to never have to work again. The freedom date then tells you the date through which your retirement savings would support you each year.  For example, if you have 100 freedom days then your spending could be covered through April 10th, each year.

How close are you to 365 “freedom days”?
