Just in case you're having a Blue Monday, please allow us to cheer you right up with this sunny news.

We finally have an arrival date for 'It's Always Sunny in Philadephia' season 15 on Netflix - and it turns out we won't have to wait too much longer.

According to the Netflix website, new episodes of 'It's Always Sunny' will be added to the streaming service on February 1, which is just over two weeks away.

In season 15 of the comedy series, which is made up of eight episodes, the five-strong group of the worst people you will ever meet, head to Ireland for a journey of self-discovery. Before touching down in the last of saints and scholars, there was a very Irish poster of the new season released.

Episodes five through to eight features the cast of Charlie Day, Rob McElhenney, Kaitlin Olson, Glenn Howerton and Danny DeVito venturing off to Ireland where they interact with a number of characters, including Irish icon Colm Meaney, whose character Shelley Kelly creates a very close bond with Charlie.

'It's Always Sunny' season 15 launched in the US last December on TV network FXX (and FX on Hulu) but this will be the first time the new season will be available on this side of the Atlantic.

Last August and September, the gang were filming in Dublin and in various other locations across the country for approximately a month of filming; a Danny DeVito lookalike was on the agenda for a stunt they were shooting.

Last year it was confirmed that 'It's Always Sunny' will run for a further four seasons, which will see the crude comedy become the longest-running live-action comedy series ever made, breaking a record that it has already set by itself.

Watch 'It's Always Sunny in Philadelphia' season 15 on Netflix from February 1.
