how to translate "in advance of" / "prior to"?

[blippy]

Just wondering what would be the most appropriate translation for "in advance (of)"/"prior (to)", for example:


1. "I will need to know at least a week prior (to) the event".

2. "In case there is a problem with the post, I am sending you this a week in advance (of the time it should be with you)"


Does it involve 事前に and/or 予告?

ﾂ〜窶楼窶堙 would work for the case. ﾅｽ窶凪?楼窶堙 isn't always necessary. (窶能ﾂ債 means "notice in advance".)

1. ﾂ渉ｭ窶堙遺?堋ｭ窶堙??堙?ﾆ辰ﾆ遅ﾆ停?愴暖窶堙戸?ｪﾂ週ﾅ?ﾃ披?楼窶堙俄?堙
2. ﾋ?ｪﾂ週ﾅ?ﾃ披?楼窶堙俄?倪?披?堙ｨ窶堙懌?堋ｷﾂ。
