When could I take a haircut due to sheloshes yemei hagbola. Does it start wed night or thu morning?
Answer:
For those who are stringent to refrain from haircuts until the days of hagbalah (meaning, those who keep the “second half” of the Omer), one should not take a haircut until the morning of the first day of hagbalah.
Those who refrain from taking a haircut during the entire Omer period (al pi kabbalah), should only take a haircut on Erev Shavuos, or Friday of this year.
