## What is Date Calculator PW?

Do date and time calculations, in a simple date calculator app!  Works just like a calculator!  Two main operations:

1. Subtract two dates (time difference)
2. Add days (or other time unit) to a date
3. Subtract days (or other time unit) from a date

Common uses:

"How many days until my next birthday?"
....[your next birthday] - [today] = ________

"How many days old am I?"  (or hours, minutes, etc.)
....[today] - [your birthday] = ________

"What date does that 90-day warranty expire?"
....[today] + 90 days =  ________

"When is 1 million seconds from now?"
....[today] + 1000000 seconds = ________


Power-user shortcuts:

** On startup, pressing "+" or "-" auto-enters "Today" as the first expression

** "1/1/2016" + "XX days" can be reversed as "XX days" + "1/1/2016"

** Like a regular calculator, operations can be chained together (e.g. "1/1/2016" - 50 days + 2 months - [Today]).

## Key features

- Calculate time difference between two dates
- Add days or other time units to a date
- Subtract days or other time units from a date

- Startup shortcuts for 'Today'

### 5/5 — COVID-19

*2020-11-20, version 1.7.22*

Serves my need for COVID Contact Tracing. I can type in a date for either onset of symptoms or date of exposure. From there, I can add the necessary number of days to determine the date my patients can end their self-quarantine or self-isolation.

### 1/5 — No longer working

### 4/5 — No Leap Year figured in much less YMWHMS!

*2016-02-20, version 1.5.1*

This app is a great help in determining the next date 70 days from the last date I picked up a commemorative coin or perhaps the time between two special events, I think however this app lacks 2 things: first, it doesn't correctly figure the number of days between dates if one or both are in a Leap Year such as 2000, 2008, or 2016 for example. second, why have just days when you can also have years, months, weeks, hours, minutes, and even seconds or at least a menu letting me choose between 1 and all 7 from years to seconds! Please consider adding one or both suggestions in case you happen to update this app🤗. :)Thanks very much:)

**Developer response:** Can change months/days/hours/... units after a calculation is made (when some units are displaying in the result).  If you have an example of days count calculating incorrectly, please send it to us at pluribusweb@gmail.com.

### 3/5 — Works, some problems

*2015-09-29, version 1.3.1*

First, this app comes with no instructions or documentation. It basically does let you get the difference between two dates and add or subtract an amount to a given date, all good. 

When entering a date, if you omit the year, it seems to default to 2000; the current year would be a nicer default. Fortunately there is a button for Today. 

There is a button to set the unit-- day, week, month etc. It works fine on my iPhone, but on my iPad Air, it always sets to Months and the selection box immediately disappears. Bad!

There is no built-in Help. The author Web page links in the App Store must be a joke-- they go to some unrelated blog.
