Answer 1

Try this :-)

Dim FirstDayInWeek, LastDayInWeek  As Variant
Dim dtmDate As Date
dtmDate = "15/04/2015"

The begin date of week:

FirstDayInWeek = dtmDate - Weekday(dtmDate, vbUseSystem) + 1
MsgBox FirstDayInWeek

The end date of Week

LastDayInWeek = dtmDate - Weekday(dtmDate, vbUseSystem) + 7
MsgBox LastDayInWeek

Answer 2

Try this Formula:-

=A1-WEEKDAY(A1,2)+1

Where A1 contains your Input Date.
