When we embark on a journey to foreign countries or to other places, can these be done Amavasyai days? Can any auspicious tasks be started on Amavasyai days?

According to Jyotisha shastram, Amavasyai is generally not considered an auspicious day. It is seen that when determining auspicious days, Amavasyai has been excluded.
Some statements say that Amavasyai is a day fit for auspicious tasks. But, Amavasyai can be considered only when other suitable days are not available; Amavasyai is secondary.
