Calendar Nerd

Everything you always wanted to know about calendar dates* — but did not know who to ask.

(* and many other things you did not yet think about)

The Calendar Nerd calculates

• your current age in days, or how many days it takes until your next holiday

• about the next good reason in the near future to open a bottle with your friends (because one is 22 years, 22 weeks and 222 days old — or so)

• when it's Friday, 13th next time (or Monday, 25th if you like)

• which date your day of birth was on other calendars (Jewish, Islamic, Chinese, Japanese...)

• when you and your friends become x days, weeks, or months old

• when it's next full moon, or what moon phase it was on the day of your birth

• when it's next blue moon, or when it was or will be in any year

• how many business days are between two dates, or what week number it is or was on a certain date

• how many days are left until summer

• how your date of birth is written in Roman numerals

• the dates of international commemorative days

• your and your friends' biorhythms

and much more!
