Customers at McDonald's across the US should not be alarmed if they see the restaurant chain's iconic 'M' logo turned upside down today at different locations. 

For the first time in its history, the company has flipped its 'golden arches' logo to show a 'W' in honor of International Women's Day, according to restaurant officials.

A McDonald's in Lynwood, California, which is owned and operated by a woman, first flipped its 'M' at the sign in front of the restaurant to celebrate women everywhere, the company said in a statement. 

All of McDonald's social media profiles, including Instagram, Twitter and Facebook, were displaying an upside-down logo today. 

The move was intended to honor "the extraordinary accomplishments of women everywhere and especially in our restaurants," Wendy Lewis, the company's global chief diversity officer, said in a statement. 

More than 62% of McDonald's employees are women, including six out of 10 restaurant managers, Lewis said. 

About 100 restaurants across the US plan to participate in the gesture, and customers will also see the flipped logo on packaging and crew member's hats and shirts, the company said in a statement.
