[2-7100] Reckoning of time
The calculation of time for the purposes of the Rules, or for the purpose of any judgment or order of the court, or any document in any proceedings, is governed by Pt 1 rr 1.11–1.13, which are applicable in all courts.
If time of one day or longer is to be reckoned by reference to a given day or event, the given day or the given event is not to be counted: r 1.11(2). So that if something is ordered to be done within three days of Monday, the Monday is not counted and the thing must be done by midnight on Thursday.
If the period in question, being a period of five days or less, would include a day or a part of a day on which the registry is closed, that day is to be excluded: r 1.11(3). Part 18 r 18.4, which generally requires a notice of motion to be served at least three days before the date fixed for the motion, means that if the motion is fixed for hearing on Wednesday, the motion must be served by the previous Thursday, the three days being Friday, Monday and Tuesday, the registry being closed on the Saturday and Sunday. If the registry is closed on the Monday (for example, for a public holiday) the notice of motion must be served by the previous Wednesday.
If the last day for doing a thing is a day on which the registry is closed, the thing may be done on the next day on which the registry is open: r 1.11(4).
The rules override the reckoning of time provisions contained in the Interpretation Act 1988, s 36.
[2-7110] Extension and abridgment
Subject to the UCPR, the court may, by order, extend or abridge any time fixed by the rules or by any judgment or order of the court. The court may extend time either before or after the time expires, even if the application for extension is made after the time has expired: r 1.12. For further discussion of r 1.12, see Lachlan v HP Mercantile Pty Ltd  NSWCA 130 at .
As to the extension of time for service of a Statement of Claim see Arthur Anderson Corporate Finance Pty Ltd v Buzzle Operations Pty Ltd (In liq)  NSWCA 104.
For a detailed discussion of the application of ss 56–60 of the CPA to an application for extension of time, see Richards v Cornford (No 3)  NSWCA 134.
If no time is fixed by the rules or by judgment or order of the court for the doing of any thing in or in connection with any proceedings, the court may by order, fix the time within which the thing is to be done: r 1.13.
[2-7120] Time during summer vacation
The former SCR Pt 2 r 5(1), which provided that time did not run from Christmas Day until the following 9 January has not been continued under the UCPR. The equivalent former DCR Pt 3 r 4 was repealed in 1991.
Accordingly, time continues to run.
