How to define Half day public holiday

Hi Team,

We want to define half day public holiday(PH) on 24th dec and 31st dec. In this case we tried defining public holiday by putting 2 in holiday class and assigning it to holiday calendar and then generated WSR. Still 24th and 31st is not getting considered as PH.

In our case 24th dec will be half day PH), 25th dec & 26th dec is full day PH, 31st is half day.

We got one case where in user applied leave from 22.12.2014 to 31.12.2014 and total number of absence days is shown as 6, whereas it should be 5 days.

Please suggest how to define half day public holiday.

Please give your input as this is urgent issue to be looked into.

Thanks

PP.
