Waking Up for Ma'ariv and Havdala...

If you went to sleep before sunset on Saturday and planned to wake up for ma'ariv, yet slept through the night...:
  • Say shacharit Sunday morning;
  • Repeat the amida for tashlumin; then
  • Make havdala.
Note If you did not intend to wake up for ma'ariv, don't say tashlumin at all.
