The timing for applying for a bus pass depends on your location and the type of bus pass you are applying for, but generally:

• You can apply for your older person's bus pass up to 6 weeks (about 42 days) before you reach the eligible age (State Pension age), but you won't receive it until you are officially eligible. This applies in places like Kent.

• In Hertfordshire, you can apply 2 weeks before you become eligible.

• In Lincolnshire and Somerset, you can apply 28 days before your eligibility date.

• Eligibility age usually aligns with the State Pension age, which can be checked with a State Pension age calculator or relevant government resources.

• The application process is mostly online and requires documents such as a photo, proof of age, and address.

If you provide your specific location or council area, I can give a more precise application timeframe for your bus pass.
