How long is the notice of cancellation of international flights?

If the plan is cancelled, it will usually be notified 2 to 3 days in advance. If it is a temporary change, he will notify it temporarily. For example, if a flight is cancelled due to weather, such notice may not be known until the day of flight departure. There are many flight changes now.
