Blue Monday 2025: when is it in January, what is it, is the most depressing day of the year today, and meaning

• Blue Monday is known as the year's ‘saddest day,’ falling on the third Monday in January
• Its origins trace back to a 2005 marketing campaign by a UK travel company
• While it lacks scientific evidence, the idea persists due to seasonal struggles like debt and winter blues
• Retailers also often capitalise on the concept, encouraging emotional spending to ‘beat the blues’
• But there are more mindful ways to find joy and avoid overspending on Blue Monday

Every year, the third Monday in January is dubbed "Blue Monday," allegedly the most depressing day of the year.

But is this gloomy label grounded in science, or is it merely a clever marketing invention? And how does the concept influence our spending habits?

The term was first coined in 2005 by a UK travel company, which claimed to have calculated the date using a pseudo-scientific formula.

This equation factored in variables such as weather conditions, debt levels, time since Christmas, and failed New Year’s resolutions. But while the formula gained attention, it was quickly criticised by scientists for lacking any real credibility.

In fact, its creator, psychologist Cliff Arnall, later admitted that the idea was largely a publicity stunt, but despite its dubious origins, Blue Monday has become entrenched in popular culture.

It resonates with many because it falls during a time of post-holiday blues, cold weather, and financial strain - a combination that can indeed dampen spirits, though emotions are complex and cannot be pinned to a single day.

Marketing campaigns have embraced Blue Monday as an opportunity to target consumers.

Retailers and travel companies, in particular, often promote "beat the blues" sales, encouraging people to spend on items or experiences that promise a quick mood boost.

The allure of retail therapy - the idea that shopping can temporarily lift spirits - is particularly strong on a day marketed as universally dreary.

But impulsive spending can actually exacerbate financial stress at a time when many are recovering from holiday expenses.

How to avoid overspending

Research suggests that people are more prone to emotional spending during periods of low mood, and while there’s nothing wrong with treating yourself, it’s worth doing so mindfully.

Here are some strategies to avoid overspending while still brightening your day:

• Set a budget: Decide in advance how much you’re willing to spend, whether it’s on a small treat, a meal out, or a new book. Sticking to this budget can help you enjoy a guilt-free pick-me-up.
• Seek free joys: Uplift your mood with cost-free activities such as a walk in nature, a call with a friend, or revisiting a favourite hobby. Sometimes, the simplest pleasures are the most effective.
• Invest in experiences, not things: If you do spend, consider putting your money toward experiences - like a yoga class or museum visit - that offer lasting memories rather than fleeting satisfaction.
• Plan for the future: Use January and Blue Monday as a chance to set positive goals. Creating a vision board or planning an affordable weekend outing can shift focus from the present gloom to future excitement.
