Hello Ashish,

Hope you are doing good.

The valid period time of EWS certificate is for one year. From the date of issue of certificate it will be valid for one year. For every year the EWS certificate should be renewed. As your certificate is issued on 23rd August 2021 it will be valid till the one year from that date. So it will be valid till one year.

You should renew the certificate after the one year.

Hope it will be helpful
