The Open Championship will be pushed back to August in 2028 to avoid a conflict with the Los Angeles Olympics.
Instead of its typical mid-July calendar slot, golf's oldest major will be contested from August 3-6, 2028.
The 2028 Summer Games are scheduled for July 14-30, including the golf competition at Riviera Country Club.
"We have worked collaboratively with the relevant bodies and our partners to agree alternative dates for staging our major championships in 2028 to accommodate the Olympic golf competitions," Mark Darbon, chief executive of The R&A, said in a statement on Monday.
"We appreciate the constructive discussions we have had with all of the stakeholders and believe that providing clarity on the dates now will assist with the planning of the global golf calendar in 2028. We can also confirm that The Open will be returning to its normal mid-July dates in 2029."
The host venue for 2028 has not been announced. The 154th Open Championship will be July 16-19, 2026 at Royal Birkdale and the 155th edition will be July 15-18, 2027 at the Old Course at St Andrews.
