Use google calendar and set it to 4 weeks is more... @officialjustlend

Answer:It is possible to use Google Calendar to set a 4 week schedule, and it is possible to set up a recurring event that will repeat every 4 weeks. However, it is important to note that December may be an exception due to the holidays. If two monthly rewards are to be paid out in December, it may be necessary to adjust the schedule accordingly. For example, the rewards could be paid out on the first and third week of December, or the rewards could be paid out on the first and fourth week of December. Additionally, it may be necessary to adjust the schedule to ensure that the rewards are paid out at the same time each month.
