History Buffs Pay Attention

The Calanderium App is visited daily.

As an avid history buff I enjoy learning nuanced moments and interventions that changed the future. The App selects historical topics that change daily and guide the reader to a more in-depth discussion in Wikipedia. If a subject interests you, then take the next step and further your research using other resources.

I highly recommend trying this App each evening.

Interesting, Informative, Fascinating

Few people appreciate human history because they are completely unaware of the events that have shaped our world. This app gives you a fascinating, daily glimpse into compelling historical events. Events which are as important now as they were back then. Society cannot improve if you don't understand the past.

Very Depressing, Mostly Bad News

I downloaded This app so I could look at each day and learn about major events that happened in history. Unfortunately, very few of the headlines are of a positive nature. You will see lots of entries like “Hitler takes Power….” and “Hundreds killed in…”, but very few “First space flight…” or “Pulitzer Prize awarded to…”

It seems this app skews toward sensationalized, negative, depressing, horrific events. But then again, maybe human history is all about death and destruction, with a sprinkle of highlights. Either way, I no longer want to start each day with a dose of depressing.
