Subject: [PATCH] [FIX] calendar: correct event day display in the email

This commit addresses an issue in the email templates where event start
days were being displayed incorrectly, particularly for events
scheduled at specific times in timezones that experienced day shifts
during UTC conversion. The previous implementation did not account for
the necessary UTC conversion, leading to misaligned event days in the
email content. This commit ensures that event start days are accurately
calculated based on the appropriate timezone conversion, providing
correct and consistent display of event information in the email
templates.
