"Just what I needed! Spent ages looking through date and time calculation apps before stumbling across this one by accident! Ive never seen anything this versatile or intuitive. Already found it very useful." Five star review by sparkyjf
A world first, DateTime takes the simplicity of a normal calculator and extends it to allow the calculation of any combination of dates and times (as well as just numbers).
Some Examples;
- You are in finance or law and need to know the the expiry date of a contract 120 days from today. Type "Today + 120 Days =" to see the answer.
- You know that a component is expected to last 10,000 hours and want to schedule a service in 7,500 hours. Type "Today + 7500 Hours =" and the answer, April 6th 2011 at the time of writing, will be shown.
- You are in planning and need to know how many weeks there are between the next and last Olympics. Type "7/27/12 - 8/8/08 =". The answer "3 years 11 months 19 days" will be displayed. Press the Weeks button to see the answer "207 weeks" displayed in weeks.
- You work in science and need to know the exact time one hundred and sixty five hours from now. Press the Today button twice to enter the current date and time and then type "+ 165 hours =". The exact date and time 165 hours from now will be shown.
- You want to know how old you were on your wedding day. Type your wedding date - your birth date =. You want to know how many days older your father is than your mother. Type your fathers birth date - your mothers birth date and then press the Days button to see the answer in days.
DateTime knows about Leap Years and takes them into account in its calculations. It even knows about the transition from the Julian Calendar to the Gregorian Calendar in 1582 and the missing ten days in October of that year. It will reliably make date and time calculations thousands of years into the future and the past.
Pros and cons of DateTime - Date and Time Calculator app for iPhone and iPad
DateTime - Date and Time Calculator app good for
this is the smartest app I have seen for a long time and it becomes very handz in a lot of situations. This will soon be a number one app everybody wants and has on his or hers iPhone
Tried a few calculations. I now can finally add time. Very hard with a regular calculator. I look forward to an iPad version soon.
I use this to calculate when my breaks will end when I miss them.
I cant believe how easy this is to use.
It perfectly suits my needs
This is an excellent date and time calculator.
OTOH - Its only a so-so numeric calculator, as it does not follow standard arithmetic rules. 1+2*3 should always produce 7 (seven), yet it produces the incorrect result of 9 (nine).
Does what it advertises. Calculates dates great. Its missing business days though.
I really like this date time calculator, but it would be nice to have a backspace key to correct entries and not have to start over.
Some bad moments
After I dowmload the app and pay for it, it tells me that the multiply and divide buttons cant be used with dates and times. I know that I swam for 30 minutes at a rate of one minute and seven seconds per 50 meters. Simple division should tell me how far I swam. Im not sure what the point of this app is if it cant divide dates and times.
App does not count the current month when counting months. For example, April 2011 to June 2012 is 15 months counting April but the app is giving me 14 - it does not count the initial months and that is what I paid for it to do.
This app used to be the best, but it had not been updated in years and with the more recent versions of iOS, it crashes all of the time. Save your money unless you see an update after 2016.
I have to agree with Spoinlar. It crashes on any calculation in BCE. before the update, it worked fine. I was using it for astronomical/time calculations. Not worth it to me right now. Please fix.
Wow it says it cannot divide or multiple time....seems my math teacher years ago differs with this. Last time I checked 1 hour / 2 = 30 minutes. That capability is doable unless you want an app without all the known features it most assuredly should have!
I cant get mine to work anymore- it crashes every time I try to convert months or years to days
