The #5525 Back To That Day Tour () was the twelfth concert tour by Taiwanese rock band Mayday, launched to commemorate the 25th anniversary of the band's debut. The all-stadium tour began at Taichung Intercontinental Baseball Stadium on December 31, 2023, and concluded at Taipei Dome on July 13, 2026. It spans 162 dates in Asia, Australia and North America.

Background On November 8, 2023, B'in Music announced the first six shows of their brand new tour, to be held from December 31, 2023, to January 7, 2024, at Taichung Intercontinental Baseball Stadium. Upon the conclusion of their Taichung show, Mayday unveiled five dates in Kaohsiung.

On March 17, 2024, Mayday announced seven shows in Hong Kong. On April 24, the band announced ten shows at Beijing National Stadium. In June, they announced dates in Singapore and China. From August to October, Mayday continued to add dates to their tour.

On January 22, 2025, Mayday announced their Las Vegas show. On March 30, Mayday announced eight shows at Taipei Dome, including four incorporating the new #5525+1 theme, which alternated with the standard #5525 shows throughout the schedule. For subsequent legs of their tour, Mayday continued their dual-themed concert series, alternating between #5525 and #5525+1 shows. Each theme featured distinct setlists, visuals, and narrative elements, presenting audiences with contrasting time-travel concepts that guided them through the band's past and imagined future.

On May 13, they announced twelve shows at Beijing National Stadium to be held from July 25 to August 17. A thirteenth show in Beijing was announced on July 24.

Production 5525 Back To That Day Tour was produced by B'in Live.

Mayday's #5525 tour marks their 2½-decade-long history since forming in the late 1990s. The numeral "5" stands for the character "wu" (meaning "five") in the band's Chinese name. The "525" refers to the more than 525 large-scale concerts the band have performed. "25" also refers to the group's 25th anniversary.

The stage design for the concert used the concept of a time machine to address various themes across the band's nine studio albums. In the coda, Mayday expressed heartfelt gratitude to their families, friends, and fans, reflecting on the past while celebrating the present and looking forward to the future.

Technically, the production departs from traditional 2D concert displays. The main stage features a 12-metre giant LED sphere called a "heavenly time machine" and five 5-metre 3D LED spheres. These spheres are constructed with seamless splicing to create immersive, three-dimensional visuals. The show will also have 13,000 custom-made LED display panels. In selected cities, the band travels around the stadium atop a "Mayday express bus", which will allow fans to see the members up close. Audience members are equipped with reusable interactive light sticks, which are linked to their seats via a mobile application or NFC, and synchronized with the main control system via 2.5G wireless communication. This system allows for dynamic, coordinated light displays that extend the visual experience throughout the venue.

The tour's innovative stage design has captured international recognition, winning prestigious awards including the Red Dot Design Award, iF Design Award, TITAN Innovation Award, and A' Design Award. Mark Kneebone, managing director for New Zealand at Live Nation APAC, described it as “a truly spectacular event,” adding that “the lighting, production, audience, and songs made it one of the best nights I’ve experienced in years.”
