https://answers.axonivy.com/questions/1392/get-a-work-day-in-the-past-from-a-day-in-the-future<p>I am using the following code to get a work days in the future or past.</p> <pre><code>in.terminateEndDateTime = ivy.cal.getWorkDayIn(in.terminateStartDateTime, in.days); </code></pre> <p>When I use the API with negative days, the API does not return a date in the past, instead the given (or current) date is returned. Example:</p> <pre><code>IBusinessCalendar.getWorkDayIn(-10) // returns current date, without any calculation </code></pre> <p>Have anyone an idea? THX for the help.</p>enThu, 09 Jul 2015 15:26:43 -0400https://answers.axonivy.com/questions/1392/get-a-work-day-in-the-past-from-a-day-in-the-future/1395<p>Thanks for reporting.</p> <p>I have just analysed and fixed the method <code>IBusinessProcess.getWorkDayIn(...)</code>. See Issue </p> <pre><code>#25593: BusinessCalendar.getWorkDayIn(...) with a negative relative-work-day as parameter returns passed date </code></pre> <p>It works now as exected. The following examples shows its usage:</p> <pre><code>All days of the week are working days, except the Sunday is a day off. ------------------------------------ | FR | SA | SU (day off) | MO | TU | ------------------------------------ getWorkDayIn(SA, 0) -&gt; SA getWorkDayIn(SA, 1) -&gt; MO getWorkDayIn(SA, -1) -&gt; FR (FIXED: before SA) getWorkDayIn(SU, 0) -&gt; MO getWorkDayIn(SU, 1) -&gt; TU (FIXED: before MO) getWorkDayIn(SU, -1) -&gt; SA (FIXED: before SU) getWorkDayIn(MO, 0) -&gt; MO getWorkDayIn(MO, 1) -&gt; DI getWorkDayIn(MO, -1) -&gt; SA (FIXED: before MO) </code></pre> <p>The fix will be included in the next Hotfix (5.1.6) by the end of next week.
