As a project engineer / project manager I needed an easy to use and accurate date calculator. Also since I work on a 9/80 work schedule, being able to know how ‘off-Fridays’ impact available working days was a must. Additionally, calculations must match those expensive project scheduling applications everyone uses on their desktops.
One of my dislikes with Android’s date entry is that it is limited and not user friendly.
I fixed that with a custom date entry screen that shows the whole month, and then
took it further with a better month and year selection interfaces as well.
If you still like the original Android method, it is still there, just hit the “Go To” button.
Usage:
1st select your format:
– e-Days (elapsed days) counts everyday of the week including Saturdays & Sundays.
– Std-Days (standard days) counts only Monday thru Friday (Note: Saturdays/Sundays are ignored).
– 9/80-Days counts only Monday thru Friday (skipping every other Friday) (Note: Saturdays/Sundays are ignored).
9/80 weeks work this way:
-Â 8 days (9 hrs/day), working Friday is 8 hrs for 40 hrs total).
-Â When using 9/80 – you will be prompted to enter the next off Friday for forward calculations
and to enter the prior off Friday for backward calculations
-Â Change the next 9/80 day by selecting the 9/80 button – your two options will be available
Note: only off Fridays can be selected (that’s the whole idea of off Fridays!!).
Date to date calculations:
– Pick start date then End date
– calculation is automatic
To find a date:
– enter start or end date
– select lock or float button to hold it
– tap/touch the days field (or weeks or years field)
– enter your amount (BE SURE TO TAP “DONE” TO ENTER THE VALUE).
– calculation is automatic
Menu Button:
– Reset button clears out calculations for fresh calculations
– Rules button provides a quick summary
– ‘About’ tells version info,
“support and info” and directs you to this webpage
“Email Dev” sends an email to me to help with questions issues etc
“Change Log” directs you to the change log this page lower down
