Exchange time slots and periods

The SIT network operates 24 hours a day. However, an interval is reserved for closing the current day and preparing the context for the next SIT business day.
The organization of the business days is described in the day profiles drafted as part of the Profession’s decisions regarding posting and exchange limit times, which are confirmed by the GSIT Management Committee.

The SIT network is open for exchanges six calendar days a week, with five settlement days. The SIT business day on Friday generally extends to cover part of the calendar day on Saturday. The SIT official time and date (SIT business day) depend on the legal time and date in metropolitan France (civil day). Using the FBF calendar, the GSIT Management Committee determines the calendar of SIT business days for each civil year.
