Is the London Stock Exchange open or closed?

Could you kindly clarify the current status of the London Stock Exchange? I'm interested in understanding whether it's currently open for trading or if it's closed for the day. Additionally, I'd appreciate any insight into its typical opening and closing hours, as well as any potential holidays or special events that might affect its operational status. It's crucial for me to know this information as I'm considering making some financial transactions involving stocks listed on the LSE. Thank you for your assistance in clarifying this matter.
