Sunday, March 12 marks the beginning of Eastern Daylight-Saving Time (DST) which will result in skipping the hour from 2 a.m. to 3 a.m. Once the time change occurs, this means the MiChart downtime for the upgrade will begin at 3 a.m.
For details on the impacts to MiChart, review the Spring 2023 - Daylight Saving Time (DST) document.
