How long is the criminal detention?

Hello, our country's laws have the following provisions on the court time of criminal detention: simple criminal cases, from detention to court, generally take four or five months, and complex cases can last for more than one year. According to the provisions of the Criminal Procedure Law, general criminal cases generally go through three stages, namely, investigation stage (public security organs), examination and prosecution stage (people's procuratorate) and trial stage (people's court). 1. Investigation stage: Article 154 The period of investigation and detention after the arrest of a criminal suspect shall not exceed two months. If the case is complicated and cannot be concluded at the expiration of the time limit, it may be extended for one month with the approval of the people's procuratorate at the next higher level. Article 160 When investigating a closed case, the public security organ shall ensure that the facts of the crime are clear and the evidence is true and sufficient, and write a prosecution opinion, which shall be transferred to the people's procuratorate at the same level for examination and decision together with the case file and evidence; At the same time, inform the criminal suspect and his defense lawyer about the transfer of the case. Second, the stage of examination and prosecution: Article 169 The people's procuratorate shall make a decision on the case transferred for prosecution by the public security organ within one month, and for major and complicated cases, it may be extended by half a month. Article 172 If a people's procuratorate considers that the criminal facts of a criminal suspect have been ascertained and the evidence is true and sufficient, and criminal responsibility should be investigated according to law, it shall make a decision on prosecution, institute a public prosecution in a people's court in accordance with the provisions on trial jurisdiction, and transfer the case files and evidence to the people's court. 3. Trial stage: Article 202 When trying a case of public prosecution, the people's court shall pronounce a judgment within two months after accepting it, and no later than three months. For a case that may be sentenced to death or an incidental civil lawsuit, if one of the circumstances stipulated in Article 156 of this Law occurs, it may be extended for three months with the approval of the people's court at the next higher level; Due to special circumstances need to be extended, it shall be submitted to the Supreme People's Court for approval. If the people's court changes its jurisdiction, it shall be counted from the date when the changed people's court receives the case. The people's court shall recalculate the time limit for hearing a case transferred to the people's court after the supplementary investigation by the people's procuratorate is completed.
