Unable to click a date in calendar as the link is continuously changing

Question

I'm trying to select the day in a calendar but can't because everytime i create a new workspace (new page in our UI) the Xpath changes.

Xpath

//div[@id='mobiscroll1486619404547']/div[2]/div/div/div/div[6]/div/div

Is there anyway for me to click it by class?

<div class="dw-cal-day-fg">1</div>

Edit

Selenium Script

<!--Set year to 2016-->
<tr>
    <td>clickAt</td>
    <td>//div[@id='mobiCalendarId_dw_pnl_0']/div/div/div/div/div/div[2]/div/div</td>
    <td></td>
</tr>
<!--set day to 1st-->
<tr>
    <td>click</td>
    <td>//div[@id='mobiscroll1486619404547']/div[2]/div/div/div/div[6]/div/div</td>
    <td></td>

Code from the page

<div role="button" tabindex="0" aria-label="Friday, January 1 " data-day="5" data-full="2016-0-1" class="dw-cal-day  dw-cal-day-first dw-cal-day-v dwb-e dwb-nhl dw-sel" aria-selected="true">
<div class="dw-i  ">
<div class="dw-cal-day-fg">1</div>
<div class="dw-cal-day-frame"></div>
</div>
</div>

Answer 1

Try this way, using class attribute of div tag with [3] Here, indicates index number [3] as particular day.

For example, In below xpath I have use index number as [3], so this xpath will find the third day inside your html.

//div[@class='dw-cal-day-fg'][3]
