A ceasefire has a historical meaning, generally they were considered to be a durable agreement, often as a precursor to negotiations or some other attempt to resolve the conflict at hand.
Leaders in the conflicts you're following actually have no intention of ending hostilities, the underlying contradictions that brought them to conflict are unresolved. However, saying you're granting or negotiating a ceasefire makes you look like you're trying to deescalate or be the responsible party.
So they're agreeing to them for optics, or for limited relief from some of the effects of the war. But since both sides have different agendas they're not lasting past the point of most expedience. The scary thing is that in the process they are degrading the tools and norms of diplomacy which will impair efforts to actually wind things down when the time comes.
