Because dates are required in each posts it might be relevant for the PLAYERS to know when their actions are taking place respective to the full moon even if the CHARACTERS don't know.

The times of the moonrise are in the Greenwich Mean Timezone that the U.K. is in, so everything is accurate. These are the dates from the year of First Year through 1981, the year of James and Lily's deaths.

Some of the times might be too early to see the moon due to the sun still being out, but that doesn't mean the moon isn't present.

I found the information here.

For those of you that don't understand a 24-hour clock, subtract 12 from numbers above 12, and add "pm." For example 13:19 is 01:19 pm in the afternoon. All numbers before 12 are in the am. 00:00 is midnight and 12:00 is noon.
