Importance of timezone

Taking timezone into account is mandatory each time one tries to link an astronomical event and the calendar.

Les jours commencent toujours à minuit heure locale, mais les mois sont liés à des segments solaires ou aux nouvelles lunes Theses astronomical events occur at the same moment for everyone on earth, thus at different local times. Only the days that are a solar segment or a new moon are concerned by this factor, but pour some people or situations, that can change things a lot. So it is important to consider it. Stars based on solar segments or new moons can occur that day or the day before depending on where you are on earth. Month pillar can also be different. The impact on a date can be huge.
