Set flask wtform's default date as today


A basic flask wtform with 2 input dates and a submit button will be :

class WelcomeForm(FlaskForm):
startdate = DateField('Start Date', format='%Y-%m-%d',validators=(validators.DataRequired(),))
enddate = DateField('End Date', format='%Y-%m-%d',validators=(validators.DataRequired(),))
submit = SubmitField('Submit')

How do we set default dates for the form?

Note : This is only for date and not datetime.


This is the answer to my question, hope it helps others who are looking for it.

    from datetime import datetime, date, timedelta
    class WelcomeForm(FlaskForm):
    today =
    sevendaysago = - timedelta(days = 7)
    startdate = DateField('Start Date', format='%Y-%m-%d',default=sevendaysago,validators=(validators.DataRequired(),))
    enddate = DateField('End Date', format='%Y-%m-%d', default = today, validators=(validators.DataRequired(),))
    submit = SubmitField('Submit')
