The window closes at 19:00 GMT, meaning teams - and fans - can avoid the usual late-night transfer scramble.
It has already been a busy window - for some teams anyway - but whether it turns out to be a day of transfer action or a pretty quiet one for your club, you will be able to keep across it all on BBC Sport.
Oxford United will try to get back to earning points when they visit Sheffield United on Tuesday (19:45 GMT) as they fight against relegation.
The U's three league match undefeated streak came to an end on the weekend after being bested by Birmingham City.
It keeps them five points away from safety, nine below their hosts.
Sheffield United have won nine of their last 12 league meetings with Oxford United (L3), after winning six of their first 17 matches against the U's in the Football League between 1968 and 1990 (D5 L6).
Oxford United have lost five of their last six away league games against Sheffield United, with the exception a 2-1 win at Bramall Lane in March 1999 under Malcolm Shotton.
Sheffield United are unbeaten in each of their last seven home league games (W5 D2), winning their last three while also scoring exactly three goals. The Blades last won more consecutively at Bramall Lane, while scoring more than twice in each victory, back in August 1971 (5).
Oxford United beat Leicester City 2-1 in their most recent Championship away game, and the U's could now win back-to-back league matches on the road for the first time since April 2024 in League One.
Sheffield United's Chris Wilder has won seven of his 10 league games as a manager against former club Oxford United (D1 L2), only boasting a better win rate in the Football League against Dagenham and Redbridge (80% - 8/10) than the U's (70%), among those he has faced 10+ times.
Wilder: 'We showed so many qualities'
Sheffield United manager Chris Wilder describes Millwall as 'the hardest place t win' following his side's 1-1 draw at The Den.
Millwall went into the game on a seven-match unbeaten run but were pegged back by Andre Brooks' long range strike into the bottom corner for the Blades.
Mihailo Ivanovic equalised for the hosts and neither side could manage to grab a winner in the remaining 70 minutes of the match.
"In my opinion, at this particular moment it's the hardest place to go and get a result," Wilder told BBC Radio Sheffield.
"I always think you go to the big clubs and the big grounds, no disrespect, with 30 or 40,000 capacity, maybe not that many in, but today it was a full house and they're flying.
"The way we approached the game, the way we played when we had to and when we dug in, there are so many positives to come from today.
"Ultimately, we've not got the result we were after, not for the want of trying. It's great for the young players, as I talked about before, in terms of the experience in playing here."
He added: "I always enjoy it and believe, as a player and as a team, if you can get a result here, if you can get a win great, if you can get something that's a sign of strong character mentally and physically from a team point of view."

Sheffield United manager Chris Wilder has dismissed accusations that the Blades try to "bully" opponents.
Ipswich captain Dara O'Shea told the East Anglian Daily Times his side needed to do better against "teams like that, teams who want to come and bully us", external after Saturday's 3-1 defeat by the Blades.
Wilder has taken exception to the comments, saying they show a lack of respect for his side.
"The perception of that game on Saturday is that we wanted it to be a rough and tumble game, we wanted it to be a spiky game, we wanted it to be a bitty game, we wanted it not to be a game of football - absolute nonsense," Wilder told BBC Radio Sheffield.
"I heard their captain come out and say 'Oh it's a direct game and we can't get sucked into that type of game' and I just thought it was absolute nonsense and a lack of respect really for us, if I'm honest, because the name of the game is to run around, win tackles, win headers, win races and play - and we did.
"They've got a lot of good players, Ipswich - really good players - and in my opinion they're going to go up but we asked the question and we'll get asked the question this weekend."

Image source, OptaMillwall will look to keep their quest to return to the top flight for the first time since 1990 on track when they welcome Sheffield United on Saturday (kick-off 15:00 GMT).
The Lions are fifth, six points clear of seventh and six points off the top-two. Alex Neil's side have lost just once in their past seven games (W4 D2).
The Blades picked up an impressive 3-1 win over Ipswich last time out but have struggled for consistency with four wins, four defeats and a draw in their past nine games, leaving them 17th - six points clear of the drop zone and nine behind the play-offs.
Millwall have won 1-0 in their previous two league games against Sheffield United, and could keep three consecutive clean sheets against them for the very first time.
Sheffield United won this exact fixture in the Championship last season (1-0), and will be looking to win away to Millwall in back-to-back campaigns for the first time since 2004-05 (2-1) and 2005-06 (4-0).
Since the start of last season, Coventry (25) are the only team who have won more Championship home matches than Millwall (21), with the Lions currently on a three-game winning streak at The Den.
Chris Wilder has lost three of his five Championship games in charge of Sheffield United against Millwall's Alex Neil (W2); against no other manager has he lost more often with the Blades in the second tier (also three defeats to Daniel Farke and Lee Johnson).
Alfie Doughty has made more assists than any other Millwall player in the Championship this season (5), and has only provided more in a single league campaign once in his career (8 in the 2023-24 Premier League season for Luton).

Coventry City are making progress in their talks to sign Brentford defensive midfielder Frank Onyeka before Monday's transfer deadline.
The 28‑year‑old is also attracting interest from Sheffield United and is expected to decide his future within the next 24 hours.
Brentford have made the Nigeria international available for transfer after he became frustrated by a lack of first‑team opportunities under Keith Andrews, having experienced similar frustration during Thomas Frank's tenure.
Frank Lampard's Coventry sit three points clear at the top of the Championship but have just two wins in their last six league games and have not kept a clean sheet since 26 December.
Sheffield United are 17th but remain not entirely out of contention for the play‑offs in a congested table, nine points off the top six.

Wilder: 'We were good'
Sheffield United boss Chris Wilder spoke to BBC Radio Sheffield after their 3-1 home win over Ipswich Town.
"The feel of today was exactly how I want Bramall Lane always. It was edgy, it was spiky and we played well," he said.
"We went toe-to-toe with a decent side and I believe we deserved the win.
"There's a lot of noise out there and all we can do is do our best and represent the club in the best way and put a shift in.
"I thought we got everything absolutely spot on. How we set the game plan up in terms of the press and how we managed the game... It's been a good afternoon for us.
(On Bamford's red card) "It's disappointing. I don't think it was a booking over on the far side. Just manage the game and understand what it's about."

Sheffield United defender Nils Zatterstrom has joined Genoa on loan until the end of the season.
The 20-year-old Swede joined the Blades from Malmo in August but has not made an appearance for the Championship side.
Genoa, who are managed by Italy World Cup winner Daniele de Rossi and are 16th in Serie A, have the option to make the deal permanent at the end of the campaign.
Image source, EFLA new initiative highlighting the work of football club charities has been launched by the English Football League (EFL).
'Scan to Smile' will be rolled out in stadiums across the EFL from Friday until the end of January, with supporters invited to scan QR codes on posters displayed around grounds.
Each scan will unlock a short, uplifting story from a person whose life has been positively impacted by the support of their local club charity.
The subjects tackled include mental health support, combating loneliness, improving physical wellbeing, employability and confidence.
The EFL said it hoped the initiative would use "the reach and influence of football to offer fans a moment of positivity on matchday".
Trevor Birch, chief executive at the EFL, said: "Behind every club are people whose lives have been positively changed through the work and dedication of their local EFL club charity.
"This initiative gives supporters the chance to see that impact first-hand and reminds us that football truly is a force for good."
Wilder: 'We've got to be more clinical'
Sheffield United midfielder Oli Arblaster is not able to play a great deal of minutes and players returning from injury will be managed differently in the future, according to boss Chris Wilder.
Arblaster, 22, has only been able to feature in nine games this season after recovering from a cruciate knee injury.
"If there's any criticism out there it's completely unjust," Wilder told BBC Radio Sheffield.
"Next time, if it's Oli or anyone else, I'm going to allow him to make his own way back in the time it should be for a player who's missed over 13 months with a cruciate knee injury.
"I won't recognise he wants to help the team out. I will basically say to players with that type of injury, you're going through the whole process of playing under-21s for a month and when you come back, you might still not be at your best but you won't be criticised because you'll be at a level you were close to when you came out of the team."
The Blades head coach has confirmed injured defender Tyler Bindon will miss Saturday's home game with Ipswich in the Championship (15:00 GMT).
