dateCALC (Date Difference)

THE ULTIMATE DATE CALCULATOR

Presented in a clean, modern user interface, this utility carries out all the common date related calculations – and more. With different themes available, and functions easily accessible via the pull-out Navigation Drawer, this app makes calculations a breeze. All dates are presented in their full readable format (which may be customized), detailing the related day of week along with supplementary information (which may also be customized). These details include its Ordinal Date value (the day of the year, eg. 2014-038), the related ISO Week Number (eg. 2006-W52-7) or its Relative Day Number (the number of days passed since a specific starting date).

Date comparisons automatically detail the number of days between the two dates specified, and can be customized to either include or exclude the start date in the calculations. The calculated difference is also presented in a more human friendly format, breaking the value down to either 'years, months and days' or 'weeks and days'.

The calculation of days between two given dates is made even easier by utilizing Predefined Date Pairs. These incorporate common inquiry requests (like the number of days until Christmas) as well as requests based on user definable dates (such as the number of days until your anniversary, or the number of days since your Date of Birth). So finding out your age, or the number of days until a special event become extremely easy.

Also included is a handy Easter Related Dates function that details movable dates relating to Easter. These include Shrove (Pancake) Tuesday, Ash Wednesday, Palm Sunday, Good Friday, Easter Sunday, Easter Monday, Whitsunday (Pentecost Sunday) and Whit-Monday. Dates for the current, previous and next years are all made available.
