I clicked on app help and the website was defunct so there is no way to reach out to the developer. Really disappointing and a waste of money ### 5/5 — Incredible, accurate and extremely comprehensive. *2016-09-28, version 2.50.01* This app can resolve any calendar question I can offer it. I have been playing with calendars for a long time including participating in the Y2K remediation. That got me interested in perpetual calendars, so-called Doomsday calculations and Julian Day Numbers. Any Day can replace nearly all of my various calendar spreadsheets and quickly give me the answer I'm looking for. Want to know what day of the week (DoW) an event occurred? Any Day can tell you. Want to know the Doomsday DOW for a given year? Any Day has the answer. Want to look at the month when the Gregorian calendar was first used? Check October 1582. Want to know which years have a month with five three-day weekends? You don't have to wait 823 years (in spite of what that ridiculous email says) just check the amazing Any Day. (By the way, the Y2K 'problem' bit me and many others when a drugstore chain lost all of the prescription requests on Feb 29, 2000 because it's software didn't know that year WAS a leap year.) ### 5/5 — Prefect! Perpetual Calendar *2012-11-30, version 2.40.20* AnyDay is what it's name says. It's simple, intuitive and useful. Get it! If you are an old techie you might also enjoy Interrobang's Virtual Slide Rule for iPad. It's how real men calculated to send other men to the moon and back. ### 5/5 — Exactly what I needed! *2012-05-10, version 2.30.05* I needed an app that looks up days of the week past and future. This app does that plus gives me holidays (I chose which) and moon phases, etc. This is not for notes or tasks but is just what I was looking for. Simple to use and very clean UI. HIGHLY RECOMMENDED! ### 4/5 — Not for me' *2011-09-08, version 2.30.05* I'm sure this an excellent app, but not for my needs. I want each month displayed with each day shown in a large square. I want to be able to write comiments in the daily squares. Thank you. ### 3/5 — Nice app *2011-08-02, version 2.30.05* Nice app and keeps you updates with multiple holidays... Though wouldve been better if it had the islamic holidays on it as well ### 4/5 — Where are the Jewish Holidays? *2010-12-12, version 2.10.14* Love this calendar ... adding Jewish holidays would make it perfect! ### 5/5 — Best Calendar App I have used !! *2010-05-26, version 0* SImple, clean and fast ... easy to use ... just what I wanted ... don't look for this app to be your to do list ... it's great to use in conjunction with your to do ... you can literally "fly" around this calendar from full year to the month when doing your planning ... has all the holidays. Great job! ### 5/5 — Awesome *2010-03-18, version 0* Love this app. I have been looking for a perpetual calendar for six months. This is the only one I've found and it is awesome. Thank you ### 4/5 — Very handy *2010-02-04, version 0* This was a great idea. Many times you just need to look at a date down the road like to plan a trip and having the whole year in front of you is convenient. I also like that you can see holidays really quick. I wish they would add more holidays than the generic, like boss day and admin asst day, etc. Also they should really consider adding Jewish holidays. My best friend is Jewish and it's important for me to remember her holidays. If they add those holidays it would get 5 stars. ## Frequently asked questions about Any Day ### What is the price of Any Day? Any Day is a paid app, costing $0.99.
