Try checking sy-dayst.

That's interesting, in my system sy-dayst is not set to "X". I know that our time is set from the OS level, maybe that is the reason.

*&---------------------------------------------------------------------*
*& Report  ZDAYLIGHT                                                   *
*&                                                                     *
*&---------------------------------------------------------------------*
*&                                                                     *
*&                                                                     *
*&---------------------------------------------------------------------*

report  zdaylight                               .


data: w_winter_start type sydatum,
      w_summer_start type sydatum,
      w_day like dtresr-weekday.

concatenate p_date+0(4) '0401' into w_summer_start.

do.
  call function 'DATE_TO_DAY'
    exporting
      date    = w_summer_start
    importing
      weekday = w_day.

  translate w_day to upper case.
  if w_day eq 'SUNDAY'.
    exit.
  else.
    w_summer_start = w_summer_start + 1.
  endif.
enddo.
