When does contract date start and when does clause end?

If a contract date falls on the 14th February 2015 (a saturday) does the building and pest clause (7 days) finish on the saturday 21st February 2015 or the next business day Monday 23rd 2015.



Thanks I have read this but want to triple check so not to go unconditional if before I can finish getting quotes.

Quoc
