The annual Remembrance Service and March Past will take place at the Worthing War Memorial, outside Worthing Town Hall in Chapel Road.
The two minutes silence will start on the first stroke of the Town Hall clock at 11:00am after which the Mayor's Chaplain will conduct the service.
The Worthing Borough Mayor and others will lay wreaths for the fallen and take the salute at the March Past in front of Worthing Town Hall at approximately 11:30am after the Service.
Councillor Paul Baker, Mayor of Worthing, said:
"I am extremely proud and humbled to represent my town especially in this important WW1 centennial year. I would like to take this opportunity to say thank you to the many local organisations from Worthing and further afield who continue to support our annual Remembrance Service and Parade."
