Before you plan a meeting, you should first ask yourself what type of conference call you are planning. This question also determines which participants you should expect. For example, if it is a regularly recurring meeting in the form of a weekly or monthly team meeting, you should definitely make sure that none of the people involved are permanently disadvantaged due to the time zone.
Sometimes, however, it is impossible to please everyone. If your team is made up of such different time zones that there can never be a perfect time for everyone, you should consider rotating scheduling. This way, each participant can determine the optimal time for him or her and the distribution is fair.
The number of participants and therefore the most represented region are also dependent on the type of meeting. If you are organizing a one-off conference, it is advisable to conduct a survey in advance to find out who would be interested in attending. Depending on how many interested parties come from a certain time zone, this can be taken into account in your planning. If you cannot please everyone here either, it is best to follow the majority. Ideally, however, none of the people taking part should be given an impossible time.
