Notice that we do not use a preposition with this, next or last and a time expression, e.g.:



They are coming this weekend.
(Vendrán este fin de semana.)
Can you come next Saturday?
(¿Puedes venir el próximo sábado?)
They arrived last week.
(Llegaron la semana pasada.)


We use since only with a past time or past event to specify a period up to present time, e.g.:



They have lived here since 1999.
(Han vivido aquí desde 1999.)
They have lived here since their wedding.
(Han vivido aquí desde su boda.)
Compare:
They have lived here since they got married.
(Han vivido aquí desde que se casaron.)


When we specify the beginning and end of a period, we use fromto, not since, e.g.:



They lived in Spain from (not since) 1996 to 1998.
(Vivieron en España de 1996 a 1998.)
