Display external html - or - display content based on date-range

[Michael_Thomas]

Moving my shop from embedded JS to shopify... We run weekly specials, the information for those specials (start date, end date, special information) is all stored in a database (php/mysql) and it shows current special if the current date is between start/end dates.

Is there a way to recreate a similar functionality?

Barring that, is there a way I can just include that database result in shopify without using an iframe? (it outputs some heading and paragraph tags, nothing fancy)
