Does 21 days of quarantine count as detention time?

The 21 days of quarantine does not count as detention time. Criminal detention is calculated in days. The day when the period begins is not within the period, that is, it is calculated from the day after the period begins. The expiration of the period ends on the last day of the legal period. The length of criminal detention usually ranges from 14 days to 37 days.

If the public security organ considers that a detained person needs to be arrested, the arrest shall be made within 3 days after detention. Under special circumstances, it may be extended by 1 to 4 days. For major suspects who commit crimes on the run, commit crimes multiple times, or commit crimes in groups, the time for review and approval can be extended to 30 days. The procuratorate will make a decision within 7 days to approve or disapprove the arrest.
