How long will a page parameter be valid for a particular subscription.

Hi Team

Can somebody help us understand how long the page parameter(or the data for particular page) is available in OFS.

For example. On 05/25 the page number for get events for a particular subscription is 230519-351,0. Can the same page number (with same data) be retrieved few days later, if so what is the time period its available?    

Thanks,
