Dear Sudhanshu,
Information provided by you is not sufficient. There is always a difference in the kind of leave (Earned Leave, Privileged Leave, Medical Leave, Commuted Leave, Half Pay Leave, Leave Without Pay, or Casual Leave, etc.) and rules for granting, combination, and the treatment of one kind of leave with the other kind of leave period including Sunday/off day and holidays with each other. At first, you need to know what kind of half-day leave was there before Sunday/weekly off day?
It must be remembered that casual leave is not recognized as leave like the other kinds of leave and cannot be combined with any other kind of leave. Also, a fraction of leave (half-day) is never granted under any of the leave rules, except as a part of casual leave. Casual leave, if granted for a FULL DAY followed by any kind of regular leave will also be treated and counted as a part of the kind of leave applied for by the employee. But if casual leave is granted for half a day, it cannot be treated or counted as the kind of leave that followed by any kind of regular leave.
About Sunday, if it precedes or succeeds any kind of regular leave, it is permissible to be prefixed or suffixed with the leave but cannot be treated as part of leave. Sunday is treated as leave ONLY if it happens to be in between the period of leave.
Now the question arises, if Sunday/weekly off day falls in between a casual leave and regular leave, how that should be treated or counted? So, it is very simple, when casual leave is for a full day, only then Sunday/weekly off day can be treated as a part of regular leave, and if the casual leave of half day is not treated as a part of the regular leave, Sunday/weekly off day can also not be counted as a part of regular leave or absence.
So, in your case, Only Monday and Tuesday can be treated as absence or the kind of leave granted.
