act
“act”, in relation to an offence or civil wrong, includes a series of acts, and words which refer to acts done are to be construed as extending to illegal omissions;
if the last day of the period is a Sunday or a public holiday (which days are called in this section excluded days) the period includes the next following day not being an excluded day; (c)when any act or proceeding is directed or allowed to be done or taken on a certain day, then, if that day happens to be an excluded day, the act or proceeding is considered as done or taken in due time if it is done or taken on the next day afterwards, not being an excluded day; (d)when any act or proceeding is directed or allowed to be done or taken within any time not exceeding 6 days, excluded days must not be reckoned in the computation of the time.
public holiday
“public holiday” means any day which is declared to be or proclaimed as a public holiday or which under any written law is to be observed as a public holiday in Singapore;
