IT’S that time of the year again.

Whether tomorrow's deadline day turns out to be the most frenzied date of the year or another damp squib, it is sure to get tongues wagging. 

The Premiership's top three of Celtic, Rangers and Aberdeen are among the clubs who could still have business to attend to in the next 24 hours, as they hurry to bring in reinforcements or trim bulging squads.

What time does it close?

Business comes to an end in Scotland at midnight on 31 January. This is different to most of the major leagues across Europe, which close sooner.

5pm – Germany

9pm – Turkey

10pm – Italy

11pm – England, Wales, France, Spain, Netherlands

Midnight - Scotland

In several countries around the world the window stays open past the final day of January, including the selection of leagues listed below.

2 February - Portugal

7 February - Argentina

22 February - Russia

28 February – China
