About Reserves Day

Reserves Day in the United Kingdom recognizes people who serve in the Reserve Forces while also holding civilian roles. It falls within Armed Forces Week and does not have one fixed date each June.

The UK Armed Forces Day programme confirms Wednesday 24 June for 2026 and Wednesday 23 June for 2027. A future edition must be checked against its own official programme, rather than inferred from a fixed day of the month.

Why Reserves Day matters

The recognition draws attention to reservists and to employers and families who support their service.

Activities may include wearing a military uniform at civilian work where appropriate, workplace thanks and local events; participation is voluntary and should respect workplace requirements.

History of Reserves Day

An Armed Forces Day organizer account says the first event under the Reserves Day name occurred in June 2015, replacing the earlier Uniform To Work Day name.

The Ministry of Defence confirmed the 24 June 2026 observance in a written parliamentary response. That verifies the 2026 date but does not establish a fixed annual June date.
