Update : 25-12-2019

This is the words from Sciter's Web site,


Sciter brings a stack of web technologies to desktop UI development. Web designers and developers can reuse their experience and expertise in creating modern looking desktop applications. Various GUI frameworks offer different UI declaration and styling languages, such as QML and XAML (Microsoft WPF). On the contrary, Sciter allows using time proven, robust, and flexible HTML and CSS for GUI definition and GPU accelerated rendering.
Before using sciter I already tried other alternatives but none of them was satisfactory as an example first i tried andlabs/ui libraryi already have written a post on it. You can read it on post gui programming with golang.  But this library is still under construction and has no support for production apps.
Secondly, I go for electron but the problem was my simple calc like the app was of size 150mb. Which is 15mb of go and other was the electron. 
Before some time I found another alternative, s…

Find count of day differance between two dates

In golang there is no direct way [ atleast i don't know ] to find count of differance in days between two days. So, I do it the way might every one does [ except who has already faced this ].


Partial Solution


What I does is just find out duration differance of two dates using sub function.

differance := time.Now().Sub( startTime )
daysCount := int(differance.Hours() / 24.0)

It might seem ok. But, there is a problem with this solution. 

Let assume, startTime is 2018-02-02 23:59:59.  

In this case daysCount will be 0 on next day [ 2018-02-03 ] until time is 2018-02-03 23:59:59.

Perfect Solution

Simple solution is just normalize startTime to starting of that date.

normalizedTime := time.Date(startTime .Year(),startTime .Month(),startTime .Day(), 0, 0, 0, 0, time.Local)
differance := time.Now().Sub( normalizedTime )
daysCount := int(differance.Hours() / 24.0)

normalizedTime is startTime but at starting of date.

So, Now we are substracting time from 2018-02-02 00:00:00 instead of 2018-02-02 23:59:59
