You can update the Date and Time in Word when you open it. There are two steps involved here:
To add a date that Word will updated automatically, you need to insert a ‘field’.
1. To do this, go to Insert, Date and Time and choose the format you want.
This inserts a field in the page which displays the time. This time, by the way, is determined by your computer’s clock.
2. Check “Update Automatically” so that it will update when you print.
The second approach is if you want to change the format of the date field or work with the other features.
To do this:
1. Click File, Insert, Field, Date and Time.
2. Select Date from the field names list and pick a format that suits your needs.
Tip: to manually force an update, click in the date and press F9.
