# Date and time substitution tags for rescheduling templates

**Rescheduling templates must use different date and time substitution tags** than the [substitution tags used in the confirmation templates](https://www.tucalendi.com/en/s/email-notifications/use-replacement-tag-customers-local-time-booking-notifications).

This is because when a client reschedules an appointment, they can set both a **new date** and a **new booking time**. To avoid mixing these up with the original tags used in the confirmation templates, **you need to use the following tags in your rescheduling templates**:

## Substitution tags that refer to the initial booking

In the rescheduling template, you can let customers know the **date and time they originally booked**.

For this, use the following tags:

- **customers_old_date**: the customer's original date
- **customers_old_time**: the customer's original time

## Substitution tags that refer to the new booking details

To avoid any confusion, your rescheduling template should show the **date and time of the booking after it has been rescheduled**.

The tags that show the new date and time are:

- **customers_new_date**: the customer's new date
- **customers_new_time**: the customer's new time

> [!WARNING]
> These substitution tags are **only valid for rescheduling templates**.

Using these substitution tags in your rescheduling templates ensures that the **correct date and time** appear in the emails customers receive when they reschedule a booking.
