Researchers have worked out that today is the day where the UK is at its most melancholy with concerns about debt, loneliness and seasonal affective disorder having an impact.
Manchester and Leeds topped its list of the places which suffer worst from the January blues.
Charity Christians Against Poverty is using the day as an opportunity to encourage those struggling with their finances to seek help.
Speaking to Premier, Dan Kelly from CAP said: "There's always a solution. The earlier someone realises 'this has gone behind my control, I could do with help', there's no shame in that.
"The quicker they accept that and seek help, the quicker they're going to be able to get out of that situation."
Supermarket Tesco is also hoping to help Brits banish the blues by giving away free fruit today between 3.30 and 5.30pm.
Tesco's corporate responsibility director Josh Hardie said: "We know today is the day people are most likely to be feeling the January blues, and we hope a free piece of fruit will help our customers feel a little bit happier as they shop with us."
