Time is, of necesity, an illusion in any soap that's not broadcast 7 days per week. For example, each episode of a soap might cover the events of a single day. If a soap is only transmitted twice per week that means that over the period of a month (in the real world) events have only moved on by about 8 days in the soap. However if some episodes of the soap only recount what occurs during the daytime, with the next episode telling viewers what happens that evening, a soap might have only moved on by a few days over the course of a (real) month.
So scriptwriters tend to avoid specific references to time and just assume that every day is a 'standard' one. (You can watch some soaps for months and find that people are going to work every day and that weekends never seem to happen!).
Of course, there's one big exception to the 'time free zone' of soaps. Where would Eastenders be, for example, without a major event occurring on Christmas Day?
