LOL I just came back today when I realized how waaaaay off I was!!!
Not even really sure how I managed that, I literally have a calender right in front of me. WELP.
That would still put you at a needing a deficit of 744 calories per day, which is totally doable with exercise. (And this time I
double checked, lol.) The recommended maximum rate of loss per week is slightly less than 1 kg, which requires a 1000 calorie deficit per day.
If you eat 1500ish calories per day already, I would guess you're pretty close to a 1000 calorie per day deficit. That's going to leave you some time to adjust things before your deadline, just in case.
Honestly, it looks like you're good to go.
